I just got a pair of Specialized pro shoes, but I am having trouble adjusting the cleats. My left foot hits the crank arm, so I have put the cleat heel out, but it still rubs. This is my first pair of shoes that have a ratchet system strap. I never had this problem with my all velcro shoes. I can see that with the ratchet system the screw area sticks out. My solution has been to put ducktape where the rubbing occurs, which is not a cure for the problem. Please help.
