That could just be because I walk around alot and work LONG shifts, otherwise great shoes They were to big. Ordering another pair so I can have a backup pair. I figured it would keep our lunches cool. Cute but had to return them. Will be returning for smaller size. Great protective case for your AirPod, very durable and protective. These would have been so much easier. They cushioning inside has really deteriorated and I hadnt worn them "hard" before summer. It definitely is chewed on but it is whole, not gutted and missing parts, but whole.
