I just started with Sidi shoes and Look Keo pedals a couple of weeks ago. As it turns out, the shoes are too big for me but I didn't decide that until wearing them several times...I guess their not supposed to fit loose like running shoes. I've ordered a smaller size road shoe on-line so if anyone is interested in a 'gently used' pair of 42.5 Sidi road shoes, just email me off line.
