Steve I.wrote a review of Sidi Genius 7 Carbon Cycling Shoe - Men's on February 4, 2020
Fit: True to size
My main concern in trying a SIDI shoe was that the reviews are all over the place on reports of their accuracy in sizing.
I've used Shimano shoes for 12 years, in part, because I can rely on their fit being consistent every time..
I just got these SIDI Genius 7's and their size 46 is spot-on. They're a true size 46 (a US 11.5 regular width). Or at least SIDI's 46 is equivalent to Shimano's 46. No squeeze. No pinch.
I'd wear them as slippers if I wouldn't slip and break my neck. They're that comfortable!
That's all I can share for now. I'll let you know in 20,000 miles if they hold up to everyday riding.
