I've been wearing Specialized Body Geometry shoes for a few years, but they always pinched my toes a bit and the Boa dials always seemed to slip a step or two when walking. Ride. After my experience with Specialized shoes, I was hesitant to go back to using Boa closures, but Boa dials on Sidi Genius shoes are so much better! They're not as prone to slipping and there's a release button so you don't have to turn the boa's handle against the ratchet to loosen it. These are the most comfortable cycling shoes I've ever had.
