Purchased these for my mum who suffers terrible with plantar fasciitis, she said since having them it has been much better than without them, and its a pleasure to be able to walk without being in excruciating agony which is fantastic news... Didn't think such a small item would make such a difference, now have purchased another three pairs for her to save having to keeping swapping them about,she even has a pair in her slippers, would highly recommend anyone suffering with this awful, debilitating pain, she’s been given a new lease of life
