I'm a standard size 8 and these def felt small/tight. I even felt like the bottom was too heavy for the skinny straps that even with the good arch support these would be bad for my feet/back. Def not what I was hoping to feel in a $70 pair of flip flops. Will try a size 9 in a style with wider straps to support the weight of the bed of the shoe. My husband swears by his all leather Olukai flip flops and we both have high arches.
