I'm currently riding in a pair of MTB shoes, size 39, which have never felt as comfortable as I'd like. I searched for new cycling shoes for six months before I finally found a pair that felt like they had enough room in the toebox. Broke the sesamoid bone in my right foot several years ago (run over by a tractor trailer loaded with sandbags -- ouch!) and have had issues finding shoes that are roomy enough since then. Tried Sidi Megas, both men's and women's -- not enough room. Several people recommended Specialized for their wide toebox -- not enough room. After months of trying on shoes, slipped on a pair of Shimano SH-R085 road shoes, and it was LOVE! I knew they were going home with me as soon as I put them on.
