Eric W.wrote a review of Sidi Drako SRS Push Cycling Shoe - Men's on October 6, 2015
Familiarity: I returned this product before using it
A little background: I've been using Sidi Dominators for the last 6 years. They fit great and work well, but are worn out. I started road biking about 5 years ago and have good luck using MTB pedals and shoes on the road bike. While I'm not a major weight weenie, I'd still like the lightest MTB shoes possible so I'm not significantly disadvantaged in road bike events.
Sidi indicates the Drako is 100g lighter than a previous models weight. Unfortunately Sidi does not publish the actual weight of their shoes. I even emailed them to inquire and got no response. The Drakos arrived today so I put them on the scale. For comparison, my old Dominators weigh 380g each (size 44.5). I figured the Drako will come in at about 280g (based on Sidi's claim of shaving 100g off of a previous model). The Drakos, weigh 375g each. No real weight benefit compared to the much cheaper Dominator. For an expensive high end race shoe they are a bit on the heavy side.
For comparison to other major manufacturers advertised weights for their top of the line, carbon sole MTB shoe offerings: Shimano XC90 and Giro VR90 both claim their shoes to be about 315g per shoe. Specialized SWorks 335g. All weights are without pedal cleat.
The Drako is a nice looking, stiff soled MTB shoe. With the ratcheting dials and the adjustable heel collar they have a nice amount of adjustability and fit me well (my foot is on the wide side with a big instep). Unfortunately they are just too heavy considering the price and what the other manufactures offer. I'm sending them back.
