I bought these because I got plantar fasciitis 2 weeks before a Disney vacation. I actually googled "best shoes forplantar fasciitis" and read several articles. Olukai sandals were recommended in every article. I bought this pair and a pair of Olukai Upena sandals. I like both but the Upena was a little more comfortable for me. I have narrow flat feet so they might not fit everyone else as well as they fit me. The straps were snug the first day I wore them, but never uncomfortable. By the 2nd day they felt great! These are very comfortable shoes. The arch support might be a little too firm for some. I couldn't wear these as long as I could wear the Upena style for that reason. I was able to walk 4-5 miles per day in them with no problems though. No blisters!
