I bought them mainly as an alternative to slippers. What an amazing solution, they are so comfortable, so light and so breathable! My only complaint is that the hole is already starting, see picture. That may be because my toenails were a bit long, but I still didn't expect the hole to form so quickly. They're supposed to be casual outdoor shoes, but considering how easily they puncture when worn indoors, I'm suspicious. However, I still recommend them for indoor or outdoor use. Considering the price I wouldn't mind buying a pair every year and given the development gap I probably have to LOL.
