Glad to hear it worked out for you, molliewog!

I have relatively narrow feet (B, but B-!), but I have very narrow heels and a wider forefoot. I live in sneakers or Keens because if something's narrow enough for my heel to not slide out of it, it's way too tight in the toe box. I have a pair of Specialized MTB shoes that I like, but they are too loose in the heel and I have a feeling they're not stiff enough.
