Nike Calm Slide Black

Go one size up if it feels too small. The sole and upper are made of different materials, so durability isn't an issue. It's easy to style with various outfits.

These slippers are really great—they're waterproof, comfortable, and don't hurt my feet at all. The raised part in the middle gives a nice, supportive feeling when I walk. The only thing is that the size runs a bit small, but they're also very easy to keep clean.
