The Wire was the top Sidi road shoe till the Shot was released. The Wire retains the elite features that make this model one of the top road shoes in the world! Constructed of a solid or a perforated (AIR) “TechPro Microfiber” upper, this material offers the most technical versatile synthetic leather, incorporating performance features of stability, H2O repellency, and durability. Offered in numerous colors and available in standard men’s and ladies’ sizes only. The handmade vented carbon outer sole provides excellent power transfer and 4-season air circulation to the cyclist’s foot. Sidi’s exclusive “adjustable heel retention system” ensures no power is lost due to slippage on each stroke of the pedal while the classic Sidi “soft instep closure” system combined with the “single techo-3 push” boa-type wire closure ensures a comfortable overall fit.
