They're definitely not Birkenstock quality. The material started peeling away from the foot bed within only a few weeks of having them. I think they'll survive the Summer only, but for the price, I suppose that's not so bad. I will say, they are very comfortable. The size is almost spot on. I read other reviews that said they ran large, which made me order a half size down. If I order again, I'll be getting my typical size instead, as these fit a bit too small on me.
