I've tried Sidi wires, Shimano R320's, Vittoria Evo Horas, and many others. These are the best shoes I've ever tried. They weren't the best right out of the box but after a few heat moldings they are amazing. I heat molded them, rode about 70 miles, heat molded them again, rode another 50-70 miles, and then heat molded them again. They get better and better. The bath tub shape is crazy stiff too. No wonder guys like Bradley Wiggins and Rui Costa used Bont.
