Here's what others have to say...



  • Familiarity:I've used it several times
  • Fit:True to size

I bought these as a gift for my GF and the first thing she said was "shiny". She preferred matte shoes but ended up using these anyway as her first clip ins. She hasn't had a single complaint...although sometimes commenting on the shine of the matte black.


She loved them!

Ordered these shoes for my wife's spin class. She tried a few different brands, but the fit wasn't to her liking. One minute after she tried the Giro's on, she was sold. True to size.

Color is pretty bright, lots of white with a nice accent color in a dark pink.


Right On

A recent injury prevented the use of my carbon road shoes(per PT). Research/reviews are 'right on' regarding the stiffness of this shoe. Nice snug fit, breathable (very important in this TX heat) and lighter than my Shimano MTB shoes. Only wish would be something other than black available. Apparently the white was very popular.
