Blder Sevenwrote a review of Sidi Genius Fit Carbon Shoe - Men's on July 21, 2016
Familiarity: I've used it several times
Fit: True to size
Picked up the white/red/black to replace my 10 y/o Sidi road bike shoes. I loved my old pair because they had the 3 velcro straps, for easy adjustment.
I found this model to be lighter and stiffer than my previous pair of Sidis. I don't know if the stiffer feeling is a good thing yet, but certainly each time I wear them, they soften up and seem to mold to my feet.
This model seems to have less material and is better fitting than my previous model.
I wear a size 12 or 12.5 in regular shoes and got the Sidis in a 46.5. I can barely fit an index finger behind my heel when the shoes are on and don't find my toes are crunched.
I've worn these on long climbs, on long rolling rides, and find they get more and more comfortable the more I wear them. i have about 500 miles on them now and am very happy with the purchase. The white/red/black looks awesome and will match any kit. I contemplated the Yellow fluo also. I definitely would not recommend the all black color because that is simply too boring.
