My sister in law told me about the brand. I am dealing with Plantar Fasciitis over 1 year and been wearing tennis shoe's every day. I am tired wearing tennis shoe's every day, so I tried these out. I am very impressed with these flip flops, they are so comfortable and it doesn't hurt my heel at all. They are  kind of spongy for my feel. I am defiantly will buy more of these flips flops.. I am just happy to get to wear these in the summer and not tennis shoes. They are kind of expensive, but worth it.
