I currently use SPD cleats and have found my very stiff soled Specialized shoes are somewhat better than a more flexible pair of Shimano shoes. Tightening the shoes excessively stops the foot movement but is no more comfortable. I've used the same cleat positions and bike fit for several years and have not tried changing the cleat positions yet.
My local bike shop has heard of this problem before but had no ideas on a work-around. Does anyone out there have any experience with this? Thanks in advance!
