I started wearing Orthaheel sandals a couple of summers ago. I bought one pair and was hooked! I had plantar faciitis in both feet and tendonitis in my left ankle. My pediatrist was trying to get me to look at custom orthotic inserts ( meaning no more sandal wearing) or orthopedic shoes! YUK! Then I found Orthaheel. I buy a new pair of sandals for Summer and a new pair of closed shoes for winter every year. People constanly say"They are so cute, where did you get them?" They feel great on my feet, no more heel pain, no more ankle pain. They run pretty true to size, maybe a little narrow at first but they do break in. Also may take some people a couple of weeks to get used to the orthotic sole. Wear them a couple of hours a day till they feel right. I just love them and I'm trying the Boots this year for winter!
