Introduction
The Sidi Genius 6.6 lies second in Sidi’s road shoe hierarchy. Built on the ‘Sidi Full Carbon Sole’, which is the same platform found on their flagship shoe: Ergo 2 Carbon. With two ‘High Security Velcro’ closures on the instep and the and ‘Caliper Buckle’ ratcheting, top enclosure.
Sidi is one of the most aesthetically appealing cycling shoe brands I’ve seen. When the Genius 6.6’s landed in my hands, I was almost reluctant to get them dirty. They are beautifully made: flashy, classy, and robust. However, as soon as I was home, I buttoned up a new pair of cleats for my ride the very next day. I enjoyed breaking them in for a couple weeks before racing in them in local road races and criteriums.

I am not sure if you were aware of this or were actually referring to this in your article but the Caliper Buckle DOES let you loosen quite finely by pressing downward on the black, square “button” (if you will) on the opposite side of the buckle relative to the ratcheting tightening lever. You did mention that you were a “chronic over-tightener” and I believe I am too, but I’ve put about 1000 miles on my Sidi’s over very rough terrain and they have never jumped more than one click when adjusting with the fine adjustment button.
