I've been wearing sandals for over 10 years, mostly vibrating five toes, and I have to say I've missed the Merrelle sandals. The toe box is wide to avoid folding the toes like other sandals. I was hesitant about which size to take, even though I've been buying sandals for a long time and I know my ideal size. These tunes are true to size and other reviews said they most likely never wore barefoot shoes. I like my spinning shoes along with my five toes.
