I run about 5-6 days a week and alternate between this pair of shoes and another pair of Saucony running shoes. Saucony is doing well. This couple is already getting holes in them. And as others have pointed out, the tongue is like a knife. I don't know what they were thinking when they were made. I didn't want to use them for about two weeks. Over time, the language began to wear out. But for about two weeks it was such a nuisance. I first bought these shoes because they had a wide toe box, which they do. It's nice. But I won't buy these again. save your money There are other shoes that are more durable and won't cut you in the process. Altra if you are reading this. Fix the tongue and make the shoe more durable and I will buy it in the future. At the same time I go with Topos and Saucony.
