I have a AAAA heel and these boots fit fine. Not too snug and support great. Very nice arch support also. When I first saw them I thought "oh poo, another pair of girlie boots" but when I tried them on I was sold. I am an outdoor gal and want my clothing and footware to be just as warm as a male. I resent it when they put frills in womens outdoor gear instead of function. Hard to find great items but these are boots you won't be sorry you bought. The nylon materal is very flexable and with the tie in the front very adjustable. I love mine. Hope this helps.
