If you're thinking about starting CrossFit and don't know which shoes to wear, you're not alone. It's one of the most common questions from people walking into a box for the first time, and the answer matters more than you'd think.
The right shoe isn't just about comfort. It's stability, safety and performance in movements that ask a lot of your feet in completely different directions.
Why running shoes are not right for CrossFit
The first temptation is to use the running shoes you already have at home. It's a common mistake, and it's easy to see why.
Running shoes have a thick, cushioned sole, designed to absorb impact in a straight line. In CrossFit, your foot needs lateral stability, contact with the floor and a firm base to lift weight. With a very cushioned sole, you lose control and efficiency, especially in movements like the squat, the deadlift or the snatch.
What to look for in a CrossFit shoe
Flat sole or low drop
Drop is the difference in height between the heel and the toe. For CrossFit, a low drop is ideal, between 0 and 6mm, allowing a more stable and natural position during lifts.
Firm, stable sole
Unlike running shoes, you don't want too much cushioning. You want to feel the floor, especially when you're lifting. A firm sole transfers your body's force to the floor better.
Durable but flexible upper
CrossFit combines running, jumping, rope climbs and gymnastics movements. The upper has to withstand friction, twisting and repeated impact without losing its shape.
Lateral support
Lateral movements, changes of direction and exercises like the box step or the lateral shuffle need support at the sides of the foot. A shoe without that support raises the risk of sprains.
Light weight
In a CrossFit class you might run, jump and lift all in the same session. A lighter shoe helps with the transition between movements and reduces fatigue throughout the workout.
Types of CrossFit shoes
Functional training shoes (the best option for most people)
They're designed specifically for CrossFit and functional training. They combine a stable sole, a low drop and a tough upper. They're the most versatile choice if you do CrossFit regularly.
Examples of features to look for: a firm rubber sole, heel reinforcement, breathable mesh and a weight under 350g.
Weightlifting shoes
They have a raised heel (usually 19 to 22mm) that makes the squat position easier and improves performance in the Olympic lifts. They're excellent for strength work but no good for running or gymnastics. Used by more advanced athletes in specific sessions.
Minimalist shoes
Very thin sole, zero drop, minimal weight. They increase the feel of the ground but require gradual adaptation, so they're not recommended for beginners.
How to tell if your trainers are hurting your training
Watch out for these signs:
- Instability in squats: the heel lifts or the knee caves inwards
- Foot or ankle pain after training
- A “sinking” feeling when lifting weights
- Uneven wear on the sole
If you recognise any of these signs, it's worth checking your footwear before blaming your technique.
And for the first class?
If you don't have CrossFit shoes yet, you don't need to buy anything before you try it. For your first class, any gym trainers with a fairly flat sole will do. The coach will assess your movements and can advise you on what makes most sense for you.
At Revolution Fitness, the first class is free with no commitment. Come and try it, in the trainers you already have, and see for yourself whether CrossFit is for you.
