Excellent quality, fit and comfort. Good feedback when running and excellent cushion for long runs... Very good toe box room and comfortable upper. This shoe also looks amazing in the blue and it is also breathable in the toe box area.. very soft upper and good heel support. There is no annoying medial arch support digging into your arch.. it is just comfort all around.. not clunky but a firm ride.. love this shoe.. it's a little firmer than the 880v10 but I like that.. highly recommend for flat feet that do not over pronate.. that is people with flat feet that walk netural..
