Familiarity: I've put it through the wringer
Damn good shoe! I've been racing bicycles since I was 18 y/o. I'm now 47 y/o. I started out using specialized shoes. It's very hard for me to make a move to a new brand of shoes. I went to Sidi in 1996. Since this time, my feet have been extremely comfortable. I can stay in these shoes and on the bike for hours with out developing a hot spot, heel slippage, numbness in the toes, or any other annoying sensation. They are warm when needed and cool when needed. The Sidi 6.6 Carbon Speedplay shoes are significantly lighter than the Sidi Ergo 3 Carbon shoes. The roomy toe box creates a long comfortable wear. The heel box provides an incredibly stable sensation around the heel leaving all of your concentration for the sprints and hard climbing vs. worrying about power transfer to the pedal due to heel slippage. As far as credit to my shoe critique, I've been the Arizona state road race champion, 40k time trial champion, and hill climb champion in the Cat. 3 Div. In 1991, I won the Triathlon Long Course Championships Amateur Div. at the Texas Hill Country Triathlon and in Oct. of 1991, I competed in the Hawaii Ironman World Championships. Thanks for a great shoe Sidi, and thanks for a great deal Backcountry!
