These are my favorite sandals! So comfortable! True to size. I have normal feet. Normal arches. No bunions, no hammertoes, no plantar fascitis. My food width is B, which is regular. I am on the wider size of regular/B. If shoes run small I wear a 9W or a 9.5B. These fit like they were made for my feet. Now that I am older (54) I enjoy the arch support. I've worked on my feet all my life, a teacher and a sales associate at a department store. Always on my feet. Orthaheel allows me to wear orthopedic sandals that are pretty!
