Hi, I had the shoe recommended by a guy at Arosports in Hitchin. I did a test on the running machine and based on the test he recommended the GT2140. He did say that I do over overpronate but not too much. By leg strain I mean strain all over my legs, apart from feet. Strangely enough I feel it more after the run, when I walk.
I ran about twenty years ago and never had these problems so I definitely think it is the shoe.
