What is CrossFit?

CrossFit is a high-intensity workout and sport which was developed in the early 2000s by Greg Glassman. It has gained immense popularity throughout the world for its emphasis on functional fitness, varied workouts and intensity. The reason CrossFit works so well is because it focuses on movements you would make in everyday life. For example this could involve squatting, lifting, pushing and carrying. This is to get individuals to become better at real-world tasks by improving their overall strength and mobility.

Other components of CrossFit include 'Workouts of the Day' or WODs. These make each day's workout varied. They challenge participants to adapt and improve their fitness throughout a wide range of activities. This is the core mantra of CrossFit - stopping boredom and plateaus. Also to prevent boredom many CrossFit gyms (referred to as 'boxes') build a strong sense of community among members. All with local and global competitions, and their annual CrossFit games.

Ultimately, the goal of CrossFit is to scale up overall fitness, focusing on ten physical areas: cardiovascular/respiratory endurance, stamina, strength, flexibility, power, speed, coordination, agility, balance and accuracy.

The best overall trainers for CrossFit

The Reebok Nano series has been a long favourite among CrossFit enthusiasts, and the Nano X3 upholds the reputation with flying colours. The chances are if you've been to CrossFit, at least one person in your group will have been sporting a pair of these. There's a reason as to why we've given the Reebok Nano's the title of 'best overall CrossFit trainers' and that's because they are a true all-round trainer.

Excelling in areas like stability, support and durability, the new Lift and Run Chassis system in the Nano X3's has got your back when it comes to lifting weights, tackling a WOD or going for a run.

Unlike most trainers, the heel piece takes on a dome-shaped form, which compresses under the load of your foot when lifting to create a stable platform. New to the Nano series, it then cleverly undergoes a softening process when you lift off and begin running. This interesting, yet remarkable, design is built on award-winning Floatride Energy Foam, engineered to transform the way you run.

Pros

  • Part of [REE]CYCLED - made with at least 30% recycled or repurposed material
  • Flexweave woven fabric to provide added breathability
  • Dome-shaped heel piece to improve responsiveness

Cons

  • Difficult to get hold of due to popularity
SizesUK 2.5-9.5
ColoursAvailable in more than 20 colourways
  • Customer review: "The Nano X3's are the best CrossFit shoes, hands down! Comfortable, secure fit without being too narrow or tight. I sized down half a size. My favourite shoes for CrossFit! Great for running, rope climbs, jumping and lifting!"

The best CrossFit trainers for stability

Nike Metcon 9
Price: £90.99 (was £129.95)

Nike came into the world of CrossFit with a bang with its Metcon shoes, showcasing dedication to intense workout regimes. Building upon the excellence of its predecessor, the Metcon 8, these trainers are a powerhouse, offering users exceptional stability and a low, flat and wide heel which is perfect for lifting heavy weights. A clever moulded rubber wraps around the middle of the foot to the upper, with the aim of enhancing support, making rope climbs a breeze. Meanwhile, the dual-density foam midsole provides responsive cushioning for continuous cardio and movements, making them a great option for various CrossFit exercises.

If this wasn't enough, an innovative heel plate named the Hyperlift plate, is in place to evenly distribute weight. This will provide unmatched stability during split squats and deadlifts. Hyperlift not only directs weight downward and outward, but also bolsters the heel's rigidity, to make sure you feel fully grounded and supported so you can reach your fitness potential. Plus, the durability and sleek design are just two added bonuses.

Pros

  • Improved Hyperlift plate for stability
  • Lace-lock system to help keep laces in place
  • Extended rubber wrap for support
  • Breathable and easy-clean textile

Cons

  • Some users found the trainers let them down while running due to their flat bottom
SizesUK 5.5-14
ColoursOrange, Grey, White, Black, Khaki
  • Customer review: "The improvement of Nike's Metcon 9 shoes is significant with stability and with a wider toebox to take a better grip with the toes for cleans and snatches. Running and cardio workouts are a lot more comfortable."

The best minimalist trainers for CrossFit

If you're a minimalist and prefer simplicity in your CrossFit activewear, the NOBULL Trainer+ should be your top choice. Straightforward in design but exceptional in performance, these shoes are made specifically for CrossFit as part of their NOBULL CrossFit games collection.

Featuring a SuperFabric one-piece upper, designed for breathability and to stand the test of time, your trainers will remain in perfect condition workout after workout. To find your footing, NOBULL have engineered their shoes to have a spacious toe box and a low drop to enhance your stance. On top of this, the padded heel, collar and tongue ensure optimal comfort.

On the inside of the shoe is a perforated micro suede tongue and a moulded insole to deliver comfort and, you guessed it, breathability. Rivalling the Nike Metcon 9, the lace system is reinforced with internal webbing to guarantee stability and longevity so you can feel like these shoes are a second skin for your feet.

The best running trainers for CrossFit

KIPRUN's KD900X shoes has real-life backing from athlete Yoann Kowal. He wore the trainers during the 2022 Lille semi marathon, where he beat his personal best after he completed the race in an impressive time of one hour two minutes. After the race, Yoann praised the shoes for their lightweight design and traction on the road, particularly during challenging moments on damp ground and hairpin bends.

The KD900X also take the title for the fastest shoes ever designed at Decathlon. In its quest to create the perfect cutting-edge shoe, they collaborated with Arkema to pioneer the VFOAM in Pebax material. This specialised material is engineered to be 20 percent more dynamic than traditional shoe foams.

Combined with a carbon plate the trainers are said to return a staggering 75 percent of your expended energy, so you can push your fitness even further. Continually, weighing 225g in a size eight, KIPRUN focused on choosing the lightest materials and sole to enhance your running performance by reducing energy consumption during workouts.

Pros

  • Available in both men's and women's
  • High durability: tested up to 1,500km
  • Energy return with Pebax foam

Cons

  • Some users found they weren't a good fit for wide feet
SizesMen's UK 6.5-12, Women's UK 4-8
ColoursWhite, Black, Yellow, Turqoise
  • Customer review: "This is the second pair of KD900X's I have purchased. I find the overall quality of running shoes to be very good. I used the first pair to run a near sub three marathon, so they are suitable for long distances. For speedwork they feel responsive, with a good push off from the toes. I wear a half size up from my normal shoe size and I feel this extra space helps."

The best weightlifting trainers for CrossFit

When it comes to Olympic weightlifting, the Adidas Adipower Weightlifting 3 is your best bet. These trainers are designed to provide maximum stability and grounding during heavy lifts. Boasting a raised heel and high-density midsole, they ensure your firm footing even under the most substantial weights. The canvas upper, built to withstand rigorous use, is crafted with 50 percent recycled materials for sustainably-minded CrossFitters. Moreover, the outsole is made from purpose-designed rubber to firmly anchor your feet to the floor, which offers users the stability they are looking for when completing heavy lifts.

While the Adipower trainers may not be your go-to when it comes to running or box jumps, they are unbeatable for when your WOD requires squats or Olympic lifts.

Pros

  • Canvas upper with hook-and-loop instep strap
  • Made from 50 percent recycled material
  • Locked-down feel for stability

Cons

  • High heel drop (33mm) make them unsuitable for cardio
SizesUK 3-15
ColoursWhite, Black
  • Customer review: "I got the Adipower trainers to help with my squat. These are very comfortable and the bottom of the shoe is very flat and grippy to help stabilise my feet. I was having issues with my feet sliding around. The Adipower stopped that. These helped break my plateau and I was able to squat 295 lbs for a 3x5. The make and material are noticeably high quality. The heel lift is very high so they are hard to walk in, so I can only use them for squats and then change shoes after. I do recommend these for committed weightlifters."

The best outdoor trainers for CrossFit

Saloman Alphacross 5 Running Shoes
Price: £99.95

The Saloman Alphacross shoes are a great choice for running WODs. With the multidirectional lugs on the outsole and ContraGrip rubber, its trainers are made for tackling any kind of condition with ample grip, whether that be smooth tarmac or rocky trails.

The Alphacross also features a Gore-Tex waterproof membrane to shield you from the elements, and ensure your trainers still look great afterwards.

  • Features cushioned Fuze Surge foam in the midsole
  • Enhanced grounding due to ContraGrip rubber
  • Lightweight - 304g

Cons

  • Designed primarily for outdoor use, so may not work as well during indoor CrossFit sessions
SizesUK 6.5-13.5

  • Customer review: "What I can say is the Saloman Alphacross 5 is near perfection… Very light, stable with a lot of adherence and control due to the pronounced eight shape of the sole, and the Gore Tex material make them perfectly breathable without compromise on permeability to air, water etc. An extra re-enforcement on the back makes a great difference in keeping the whole stiff and steady. To finish the inner sole and arch are supporting the foot where they should be and are breathable so you doesn't feel a raise of temperature. Great product for the fast ones."

The best CrossFit trainers for women

Although the Nike Metcon and Reebok Nano's are popular choices for female CrossFitters, New Balance target women specifically with its Minimus range as they are made for narrower feet. It also has some great other qualities, like the premium liners which allow sockless training, and a mesh upper created for a lightweight feel and increased airflow, guaranteeing cool comfort throughout every rigorous workout.

The TPU-infused design not only elevates this core durability and support, but also offers cushioning without compromising on stability. Other design features to look out for include the full rubber midsole and the fact New Balance has cleverly removed any visible sew overlays to ensure that secure fit.

Ultimately, the Minimus trainers offer a reliable and well-designed option for women looking to optimise their performance in the gym.

Pros

  • Great for individuals with narrow feet
  • Premium lining to allow for a sock-free workout if preferred
  • TPU heel clip to assist with wall push-ups

Cons

  • Some users reported there is not much cushion for your sole so they may not be the best option for running workouts
SizesUK 3.5-9
ColoursWhite/Orange, Blue/Pink
  • Customer review: "I wore out my first pair of New Balance Minimus shoes and I bought my first pair of Minimus for weight workouts, now I just love having these on my feet! Lots of toe room and I can feel the ground."

It fits like an every day shoe and I love it. It’s comfortable and feels good, secure for CrossFit workouts, which is primarily what it will be used for. It’s so comfortable and different than my other shoes, that I would wear it as an everyday run errand shoe. Very happy with this purchase."

The best unconventional trainers for CrossFit

Although we wouldn't recommend Converse trainers for extended cardio CrossFit sessions, they find favour among certain weightlifters due to their flat, non-compressive sole. The flat design plays a crucial role in sustaining proper form during movements like squats and deadlifts, minimising the risk of instability. Additionally, Converse shoes boast a low heel-to-toe drop, appealing to individuals who prefer a grounded sensation in their workouts. They also make for a budget-accessible option without compromising on performance.

Pros

  • Flat heel is great for deadlifts
  • Can get them in two different designs: low-tops and high-tops
  • Minimal midfoot cushioning won't flex while heavy lifting

Cons

  • Not cushioned or supportive for intense cardio
SizesUK 3-13
ColoursNavy, White, Black
  • Customer review: "Perfect, so cute and so good for gym. So comfy."

A buyer's guide to CrossFit trainers

What kind of trainers do I need for CrossFit?

Selecting the right trainers for CrossFit is crucial, and can be a difficult task due to the diverse range of exercises CrossFit incorporates. Look for a pair of trainers that has it all, so from weightlifting to cardio, your shoes act as a trusty companion. Our recommendation is to look out for these five key features.

Durability: CrossFit workouts can be particularly aggressive on shoes, so durability is a key element. Reinforced materials, double stitching and abrasion-resistant features can help your shoes withstand the harsh demands of CrossFit.

Fit: Fit is paramount to a good pair of CrossFit shoes. Your trainers should fit snugly but not be overtight as this will cause blisters. It's important to try them on and walk, jump and mimic a few CrossFit moves to ensure a proper fit. If you have a particularly narrow foot, there are retailers (like New Balance) who manufacture CrossFit trainers specifically for this.

Flexibility: This is a hard one to find middle ground for. CrossFit trainers should have some flexibility to allow for natural movement so you can practice sprints and box jumps. However, they should also provide enough support for weightlifting movements.

Stability: Good stability is essential for the WODs that require a lot of squats, deadlifts and other lifting exercises. A good indictor as to whether a shoe will offer stability is by looking at the base. It should be flat and solid, with a low heel-to-toe drop.

Cushioning: To prevent injury, cushioning is essential. Your CrossFit shoes should offer ample padding for comfort during high-impact movements, like box jumps. But, they shouldn't have so much cushioning that you can't gain sufficient grip with your feet.

Are cross trainers good for CrossFit?

The two are easily confused because although they sound similar, they actually refer to different types of footwear designed for different purposes.

Cross trainers, or cross-training shoes, are generally designed for versatility. Created to provide moderate support for a variety of fitness activities, cross trainers are well-rounded. Saying that, unlike CrossFit shoes, they won't excel in target areas like heavy lifting or high-intensity running.

Paradoxically, CrossFit trainers (like the Nike Metcon or the NOBULL Trainer+) are specifically engineered for the demands of CrossFit workouts. This is because they prioritise features like stability for weightlifting, durability for running and grip for rope climbs.

While you can wear cross or HIIT trainers for CrossFit workouts, but they won't offer the niche and specialised traits you may want to look for in shoes for CrossFit workouts. If you're serious about CrossFit, investing in a pair of CrossFit-specific trainers is our recommendation to reduce the risk of injury and enhance your performance.

Is CrossFit harder than normal gym?

CrossFit is commonly known for its extreme intensity, powerful movements and community, which can make it challenging to many individuals. Gym workouts are a little more laid back in the approach as they offer more customisation and flexibility to suit your personal fitness needs.

The trick is to select the approach that aligns with your own fitness goals and choose a workout that motivates you to stay consistent! Either way, CrossFit and traditional gym workouts can be effective for improving general fitness and achieving desired results, with consistency.
