I know I'm a little late to the game, but I always recommend rothys! Super comfortable and breathable. Some people with flat or high arches have some issues, but I always recommend sizing up and putting in orthopedic soles.

PLUS you can machine wash them. Aka. No more smelly flat syndrome.

They're made from recycled water bottles, so they're a perfect green option!

If you want $20 off your first pair, you can use my code!
