Nice light shoe, boas work great. Caveat I have flat feet, and corn on my right small toe. I have trimmed supplied foot bed to help with my foot issues. Nice that 2 different size arch supports are included. Carbon sole is stiff, great for power transfer. Downside stiff sole also can create hot spots. Man made upper after 2 months has not conformed to foot. I need be selective in my socks as thickness can make for an uncomfortable fit. The sale price made it a good bargain.
