Very cool. Thanks. Now to find a pair to try on.I have the Sidi Vertigo boots. I am US size 10.5, but the Sidi ran small so the size 11 worked for me. I have a large calf, and high instep, avg width. I was surprised to see how much room around the calf area was available with the mirco calf adjustment. So I think the vertigo would work for you, they are a bit wide for me so I use a thick sock.
