I have hypermobility syndrome which includes a throbbingly painful hyperflexible foot. I wiegh 175-189 lbs. I spend most of my time in a recliner with a back brace. My back specialist (Ph.D. in spine biomechanics and head of a kinesiology dept.) wants me to walk more. I need orthotics that can support my feet and still cushion the shock of the rapid walking he wnats me to do.
What materials and at what thicknesses would provide the best 3 layer combination for a full length orthotic for my feet?
