Oh my, I had a bit of the opposite problem. I bought my usual size and a half size down to try on. My usual size was too long, and thus loose in the heel, but the half size down was then perfect for the heel and too narrow in the toes. I was afraid I would find nothing but pain if my feet swelled up in the slightest.
I also found the tongue to be uncomfortable against my angle. I don't understand the short hard leather-edged tongue on a bike shoe when you are constantly flexing at that very spot. Sure they put a slit in it to help it flex a little, but I'm not sold. A bit of neoprene, or molding/seewing it away from the ankle, or something would have been great.
I am bummed on those things, because otherwise I really liked the soles and the stiffness (as much as I could tell without using them) and I prefer the velcro straps to laces any day.
The tongue may not bother everyone (and if I give them the benefit of the doubt, I would hope that is something that breaks in and softens up and becomes a non-issue?), so if this happens to be the right shape for your foot, you may be stoked on these!
I guess overall I'd say they seem to be made for more narrow feet, or narrower toe-box.
Hope that helps!?
