I've suffered from planter fasciitis in the past, only when I put on my flip flops earlier this summer did I feel a familiar ache. I was looking for something that could relieve pain while keeping my feet out of orthopedics. Luckily I found them, I had a pair before but left them in the sun. My 5 year old grandson loves his new sandals. Moral of the story, keep them out of the sun unless they're on their feet!
