I need some wide fit road shoes. Most shoes seem to have a fairly narrow toe box, and I really need to be able to wiggle my toes around - I've broken most of the bones in my right foot at one time or another and poor circulation means I suffer really badly from numb feet. Currently using Diadora mtb shoes (not too bad) and Carnac road shoes - numb foot in half an hour. Any recommendations as to which brands offer more room in the toe area? Ideally without spending an absolute fortune...
