I tried my brand new Endura Road overshoes this morning and made a right mess of them. Because of the large amount of float my peddles (just for bonj) give it was possible for the sides of the shoes to rub against the chain stays. Result is one nice hole and one nearly worn thorugh patch on the inside of each overshoe. If you have float on your pedals then check that the extra thickness of material doesn't allow you to rub it away on a ride. If you can rotate the cleat out a bit more so the stop on the pedal comes into force before you start scrape away the cloth. Pedals are Speedplay Frogs. Bugger! Bugger! Bugger!!
