Is Flexibility in Cleats a Good Thing?

It all depends.

Cleats should always follow the foot's anatomy, and shoes should only flex where the foot flexes. The foot does not bend at the heel area, nor at the mid-foot area, it only bends at the forefoot.

That is why UNOZERO cleats only bend on the forefoot area, providing flexibility where it is desired, and stability where it is needed.

Don't compromise. Wear the best fitting cleats in the game.
