text: i normally wear a 9A or 9.5AA. AA is never too narrow for me, and about 30% of the time, AA is a bit too wide (ex: I have 1 other pair of Trotters, size 9.5AA, whose straps are a little too wide).  I can wear medium shoes only if the footbed isn't too wide and they have fully adjustable straps, and even then sometimes the overall shape of the straps and shoe is too wide. i ordered the Grace in a 9.5AA and - surprise! - they are a bit too narrow in the forefoot to be comfortable. I can only remember once in my life (and i am old and have always bought a lot of shoes, ha) that i have run across a size narrow shoe that is too narrow for me. these might have stretched enough and i got such a good deal that i probably would have tried that, except that the arch support in this shoe is so non-existent that it makes a sucking sound at the arch of my foot when i walk. I had to laugh. You know how some shoes have discernable arch support - that is, the arch part of the shoe rises up?  Well, in this shoe it caves in at the arch.  (i have medium-high arches and have to add slight to medium arch supports if i want to avoid knee pain in all shoes except for Dansko, Cobb Hill and some Eccos and Romikas.)
