Zachary N.wrote a review of Sidi Shot Vent Carbon Cycling Shoe - Men's on June 1, 2017
Familiarity: I've used it several times
Fit: True to size
This product is an upgrade on some older Sidi shoes that I've had in my arsenal for many years. My older shoes were 45 wide. After some stretching out, the wide's turned out to be too wide for my foot so I was always fully clamped in. I purchased these shoes in a 45 normal width and the fit was perfect. The toe box in this shoe is quite forgiving and I have a semi-wide foot. The adjustable heel is an nice feature and it firmly secures my heel into the shoe for all pedal strokes. The double techno push 3 system is a significant upgrade from my old, latching mechanism. It is very easy to add micro adjustments to your shoe as you ride in 2 locations.
These shoes are indeed very expensive, but they look amazing and they perform equally as well. I'm not a racer, but I do put in 100 - 150 miles/week and I'm really enjoying these shoes so far.
