I'm talking about the Adidas and Nike brand. When I go to soccer I always see the girl wear them after practice or a game. Is it to prevent athlete's foot? Or to give your feet air after they've been sweating? I have some but I don't wear them after soccer only for comfort at home

Usually they wear them because they slip on easy after taking off cleats etc. mainly used for walking to and from your practice space . So you don't wear out your sportswear .

It's comfortable, it cools the feet down, and it dries the sweat quicker.

They seem comfy, and they let your feet breathe. They're sporty but cute!

They want to be more comfy.
