Luckily we already own a pair, as Startrite don't have any more in stock.
Clarks don't make a C fitting in any of their shoes, and are limited in D fittings to 2 pairs of school shoes.
I can't get any shoe shops where they fit shoes to sell me shoes for her. I feel like shouting "is she supposed to go barefoot then?"
I've resorted to going to Brantano's and choosing a pair I think fit reasonably well. What do other people who's DC have narrow feet do?
