I have Plantar's Fascitis. I have pain in my arch and need to wear arch supports in my shoes/sneakers. But have been aggravating my condition trying to wear normal sandals. My friend gave me the name Vionics sold on Amazon and she said they were great; they have built in arch supports for sandals, flip-flops and sneakers. I like the style of the sandal and I love the firm arch support. It is very comfortable to walk in. The things I don't like about the sandal is all the straps are velcro and you can adjust each one. But the strap that secures the sandal by the ankle is very hard as tightly as I want it. I also don't know how long the velcro will last before it starts wearing out. Lastly, these sandals are great for just casual wear. I don't feel they look well with a little dressier attire.
