I recently got a pair of these shoes, perfect size. I noticed they are really hard in the heel of the shoe, like they have taken an ordinary running shoe and just removed all the padding. Strange, but I took it for a run. I noticed it slipped slightly all the way, got big blisters and can't really use them anymore.
Several of my running mates have tried them and everyone feels it slips on the heel, other than that its a great shoe.
Seems so strange to make such a good shoe and than have it be so terrible fitted, does anyone else have this problem or a solution to it?
