Sorbothane Full Strike insoles ,these were purchased to make a pair of Keen boots more comfortable .In this task they completely failed , no shock absorption ,no arch support and no heel cup . After only a two mile walk my feet were red hot ,I removed the insoles and they were very hot to touch . I have now purchased some very cheap insoles and they are a hundred times better .
Don't believe all the hype about Sorbothane .
