Great product, exactly what I was looking for. I train 4–5 times a week and was looking for a shoe that would stay stable during heavy squats and deadlifts. The Trainer feels solid, doesn't wobble, and has plenty of grip on the floor.

"Great shoe for strength training. Lots of grip and no more wobbling feet."

Lara van Dijk 2025.10.12

I've been using them in the gym for a few weeks now and I'm pleasantly surprised. The wide toebox, in particular, makes a real difference; my feet feel more natural, and I'm more stable during compound lifts.

They're comfortable and look great. Ideal for the gym and everyday use.

Sander Mulder 2025.10.08

Verified buyer

After trying several training shoes, this is the first one that truly delivers. The sole doesn't sink in, the grip is strong, and my posture feels better while training. I notice a noticeable increase in control, especially with squats and standing presses.

Rik Peters 2025.10.05

Verified buyer

Just what I was looking for for squats and deadlifts. Feels solid and stable.

Niels Verhoeven 2025.10.03

Verified buyer

I was skeptical at first, but after a few workouts, I was convinced. The Mesh Trainer combines stability with comfort, without feeling bulky. Even during HIIT and short runs at the gym, they remain comfortable and responsive.

Bas van Leeuwen 2025.09.30

Verified buyer

I've been using the CoreX for over a month now and really notice the difference compared to my old sneakers. No more tired feet after long sessions, excellent grip on various surfaces, and they look great even outside the gym. Highly recommended.

How are the shoe sizes?

The CoreX Trainer fits true to size.

So you can keep your normal shoe size.

Please note: many sports shoes run small, but that is not the case with us.

Why is the CoreX Trainer suitable for fitness?

The CoreX is designed with biomechanical insight to maximize your performance in the gym.

Four core principles were central to the design:

Wide standing surface for optimal ground contact
Low heel lift for maximum stability
ForceFoam™ sole for controlled cushioning and energy return
Reinforced heel for support during heavy lifts

The CoreX Trainer combines sneaker comfort with the performance of a real training shoe.

What is the difference between the CoreX and the Mesh Trainer?

The CoreX Trainer is the next generation of our best-selling Mesh Trainer.

The performance remains the same with the same stability, grip and support that Artin is known for.

The difference lies in the renewed sneaker design, with which the CoreX combines the best of both worlds: the look of a sneaker with the power of a real training shoe.

Are the shoes also suitable for running?

The CoreX Trainer is designed for strength training, HIIT, and functional workouts.

For short runs or warm-ups it is perfect, but for longer endurance runs (2km+) we recommend running shoes.
