For years I have squeezed my wide feet into standard cycling shoes, I wish I would have bought these much sooner! The BOA closure system is a major upgrade over my current shoes. The Kangaroo leather upper and carbon fiber sole both appear to have excellent quality and durability. The customizable carbon heel cup really does make a difference in comfort and pedaling efficiency. I cannot imagine riding without these shoes.... and ill probably replace them one-day with another pair of the same!
