Great shoes. The soles are extremely sticky. Even with a flat foot, and as someone who prefers square-toed climbing shoes, my toes don't stack up too much. There's plenty of comfort but no slippage in the toes/vamp area. I have experienced a little slippage in the heel when walking around after working up a sweat. They have stretched probably 1/4th size within a month of using them 2-3 times a week. The tongue is super comfortable and so is the rest of the shoe. They breathe well. No pinching/biting at the laces or eyeholes. My go-to gym shoes!
