They work more or less as flats. They do need a bit of breaking in, as the toes are much narrower than expected. It takes considerable effort to put them on without socks, and there’s no absorbency so definitely wear these with socks. Main reason it’s 4 and not 5 stars is because the bottom of the right shoe is already peeling off... I’ve worn them 3 times. Otherwise, they’re what I wanted.
