I purchased these because I have high arches and plantar fasciitis. While the arch support isn't as good as my orthotics, the extraordinarily cushioned footbed does support my foot well enough to make these sandals wearable comfortably. The four hook-and-loop straps make them infinitely adjustable, which adds to their comfort. One last, and all-important, feature of these sandals:  For the most part, I wear a C/D width but in these I had to order the 2E. Fortunately, Aravon makes that width!
