The sizes seem pretty wide on the top end. I wear a 12 in almost every shoe, and my foot is wide. The 47 feel narrow, but have broken in over time. I still have some discomfort as the sole does not cover my whole foot, leaving part of my outer foot to rub on the edge of the rigid sole. I tried the 48's first, and they were like clown shoes on me. The jump seemed like much more than one size. Mine are the elite touring shoes, btw.
