I had an injured disc and bad knees until I realized just how bad my body felt when I wore shoes...except being barefoot. I bought these to mimick my barefoot state that relieved my pain. They are the only shoe I wear now and I feel so free to move now. They will keep your feet warm in winter. May be sweaty in summer but the pace glove mesh lets sand in, the lithe glove is goretex so no sand.
