When Sidi re writes the book on cycling footwear, the Italian label isn't content to reserve all of that innovation and performance granting comfort to the boys. Replacing the top tier Ergo 3 is the new Wire Shoe a full 60 grams lighter than its predecessor and now with a sole and a fit carefully optimized for the foot of a woman. Sidi's previous The Ergo 3 was an incredible piece of cycling gear that re wrote the book on comfort and stiffness, but Sidi hasn't attained its dominance by resting on laurels and leaving innovation for its competitors. While the Ergo 3 utilized three different closure systems, the Wire is based around a single system: the new Tecno 3 buckle, yet another great innovation from Sidi. Most notable is now adjustment of each of the shoe's instep and forefoot buckles is significantly more intuitive and easier to do while in saddle. Loosening each buckle is a simple affair: you can pinch both buttons on either side of the buckle to unwind the line closure, or you can alternately toggle each button for extremely precise incremental adjustment.

Returning from the Ergo 3 is the superlative vented carbon fiber sole. It shares the same construction method that Sidi developed with their Carbon Lite sole, yet they've taken out 38 grams in the process. Even with the weight savings, you'll get the same kind of stiffness and razor sharp power transf...
