Eric H.wrote a review of Diadora Vortex Pro Shoes on July 22, 2015
Haven't ridden them yet, but they feel great when I try them on. Only thing I'd add is the size chart Backcountry /CC use seems to be way off. I wear a size 41 in shimano r320 shoes and based on their chart I ordered a 41. I could not get my foot all the way in the shoe- my toes hit the end before I could get my heel in. I then ordered a 42.5 and they fit perfectly.
I had also ordered a bunch of other shoes (different brands) and the only ones that fit correctly were the shimano r321. Go figure.
