Tsubo changed the design of their platform sole when they produced these. I've been wearing Tsubo's platform sandals for years, I wore an older design on a recent trip to Boston and walked the entire Freedom Trail and them some over the course of 8 hours. I bought these thinking they'd fit the same way—they don't. The foot bed is narrow (which pinches my toes), but so is the sole, by the heel (causing me to wobble on them.) Sent them back.
