“I am between a size 11 & 12, so I went with a 12 here. These are very comfortable flip flops that have support, which I've never felt in a flip flop before. Probably more accurate to call them sandals. I've worn them walking and biking, and they've been very comfortable right out of the box. I wish they came in an 11.5 size, as that would be perfect, and I would pick up more colors.”
