Good to know they seem narrow and yes Sidi is a narrow shoe which is why I have stuck with them. My first mountain bike shoes were Specialized and they had a wide heel and toe box, they blistered my feet with all the slipping. I talked to the local Specialized rep and he said only the S-Works are narrow. I will see if I can find some Mavics to try on, not sure the shop stocks the high end in women's. I like that they have a beefy sole, the Sidis have barely a step above road and it isn't too comfortable if you have to hike-a-bike. I am looking at the mountain bike shoes (Fury), I don't think I will ever wear out my Sidi road shoes.
