Derek R.wrote a review of Mavic Zxellium Ultimate Shoes on March 20, 2012
Awesome shoes, very comfortable. I usually wear an 11.5 US mens size (sometimes 12 depending on shoe). I ordered the 12's and they fit perfect. They give me just enough room for foot swell in the heat. I really like the looks of these shoes and the construction is top notch.
They have a ton of air flow to keep your feet cool, so pick up a set of toe warmers for cooler weather riding.
