I have been having "burning" and "numb" feeling feet soles for a few years now...blame it on crappy health and bourbon imbibing, but I took these out of the package, put them on and wore them all weekend. Even did some medium duty carpenter work in them yesterday. Really eased the foot pains..and feels like they are broke-in, right out of the box. Ordering another pair. I'm 6-5" and 330#...and seldom can find any size 15-16 shoes for my hooves. Well...gotta go order another pair before they are out of stock.
