Having recovered from a broken leg involving 7 breaks & 14 spiral fractures, (not skiing I might add), I was left with a very sensitive shin from the operation for metal plates. I have had to use some form of cushioning in my boot for many years. I bought a pair of Ski Angel 4 years ago & found them to be the best protection pads I have ever used, with no rubbing at all and I go skiing for two weeks three times each season. Unfortunately, I lost one of the pads having removed my ski boots in the basement hotel ski locker on the way up to my hotel room. I am so delighted & relieved to have acquired another pair, as they are so thin, but take every impact judder, without moving about to cause any rubbing friction between my shin, sock & ski boot. I cannot recommend these enough!
