Andrew Brookwrote a review of Giro Empire SLX Cycling Shoe - Men's on May 28, 2018
Familiarity: I've put it through the wringer
These things are so light! I've never owned a carbon road shoe so I don't have anything to base it on but it's like you're just wearing wearing socks and nothing else. The build quality is great and they breath really well.
My one complaint is that the carbon on the sole is not protected in anyway. I live on the 3rd floor of my building so when I go for a ride I have to walk down stairs with them on. As a result the carbon on the arch of the shoe has become scuffed up. I've put a piece of tape on the arch of each shoe to avoid any further scuffing.
I wear a 10/10.5 street shoe and a 45 fits perfectly.
