My wife wears a 5 1/2 normal shoe. Cycling shoes don't come in a wide width for women.
The local bike shops don't stock anything down to her size for a trial fit.
5 and 1/2 is a 36, go up to a 37, or 37.5? Guess we have to take a good guess and order. Thank goodness for easy return policys.
As with jjiam25, Sidi's widths work for me, cursed too with a wide width. THe other end of the spectrum appears to be Rocket, the maker of custom wide with shoes, and perhaps some stock models as well.
