My husband has plantar fasciitis. He tends to buy cheap shoes with little support but puts inserts into them to help his walking. I got him some fisherman's sandals with gel soles for summer for a Father's day gift, and he can barely walk in them. I don't know what the answer is.
We are quite the pair. I wear an ankle brace for tendonitis in my left ankle. I also have hip pain from arthritis and it feels like my left knee is going. I try to exercise a little each day to keep my mobility but I have to balance it with the pain and the fatigue.
MS combined with all of the other effects of aging is never boring.
