Love these for at home workouts, such as zumba, brazil butt lift, hip hop abs, pilates, yoga, etc. They are NOT street shoes or outdoor sneakers. They are designed to be more like "barefoot only better". They fit snugly. They are neoprene and nylon - so they do make your feet sweat and stink - but they are machine washable. My only gripe? They are way too pricey for what they ARE, perhaps a dollar's worth of raw materials used; it's really greedy to charge more than 20 bucks for these things. But dancers are accustomed to being ripped off for their shoes and leotards and costumes - so I suppose the vendors will charge is whatever the traffic will bear.
