sounds like it's not a good idea. Just so you know...I wear a 15 wide shoe normally. That equates to a 50 in cycling shoes. I have a pair of the Lake MX101's. I don't like them because I feel like I can't get the cleat far enough back. On a long ride, my toes end up getting numb. Normally, I ride with my Shimano SPD sandals. They're only 48's, but since they're sandals, I can get away with a smaller shoe. But there is not enough extra room in there for thick warm socks for winter riding...so I end up going with platform pedals and hiking shoes just to keep my feet warm.

I guess I'll keep to that plan, since there aren't alot of other cycling shoes out there for me....and I'm certainly to Fred-like to wear a pair of Sidi's....even though I know they make some big shoes. I think they would clash with my camo shorts.
