Bought these for indoor use due to achilles injury. The quality is superb. The footbed is very supportive, great arch support. I wouldnt wear these outside as any water or moisture would make them wet and very uncomfortable. Very satisfied...be careful on sizing....many retailers have size charts on their websites, but go to the manufacturers site to get the size conversion us to european etc. May run slightly small and since it is an open shoe, slightly large is bett than slightly small.
