I took my wife shopping for new road shoes. The the two that she liked best were a Shimano and a Northwave, but both "too pinchy" in the toe area. Pickings were kinda sparse do to the time of year, though.
But can somebody recommended a 3 hole road shoe that offers a wide toe area?
Find somewhere that sells men's small enough for her. Men's "normal width" is D, women's "normal width" is B. (Like bra sizes, higher in the alphabet is larger.) I switched to men's shoes a while back, and while it's a pain to call around to see who has them in small sizes, they're so much more comfortable on long rides.
I find Specialized to have nice wide toeboxes (in men's and women's) compared to Shimano; have never worn Northwave.
