I wear a 5.5 to 6 in most shoes. I take a 5 in these. This is the best deal I have ever found on these Tevas! I've tried several makes/models of Tevas and these mush strappy ones are one of my favorites. The straps do not dig, blister, or rub like I thought they would and the foot bed is soft and supportive, but doesn't seem to wear out like cushioned shoes most the time do. Good casual slip on flip flop!
