Sidi T-4 Air Carbon Composite Cycling Shoes - White/Black

The NEW T-4 Carbon Air Composite cycling shoes feature a super-perforated triathlon-specific upper for maximum drainage and ventilation, with a plush, brushed interior for sock-free comfort for fast transitions and supreme comfort on the bike leg.

Like all SIDI carbon soles, the Twelve Carbon Composite Sole® is designed for maximum stiffness and power transfer, but it's also engineered with a small degree of controlled flex in the toe area, which relieves plantar tendon strain during the pedal stroke. The SIDI T-4 Air Carbon Composite cycling shoes feature replaceable heel pads and are finished with a pull-tab to the heel.

Key Features:

• Injected carbon composite sole reduces weight without sacrificing stiffness and efficiency
• NEW Air perforated Triathlon-specific upper has a plush, brushed interior with minimal seams for sock-free comfort, and is now vented for air flow and water drainage
• Notched top strap opens away from the drive train
• Large heel loop for fast transitions
• The Twelve Carbon Composite Sole® is constructed from layered 3k weave carbon fibre and injected carbon fibre in a matrix of Nylon 12, a mechanically stable material that is completely non-absorbent to water, so it won't change rigidity from exposure to heat, humidity or from aging. It is an exceptionally light, stiff and durable sole
• An anti-slip insert in the toe and replaceable polyurethane heel pad help you navigate through transitions
• The Carbon Composite Sole® uses a standard 3-hole drilling pattern for compatibility with the best pedal systems available, and includes a printed 10 mm lateral and fore/aft cleat alignment scale on the sole as well as the Look Memory Eyelet® for easy cleat alignment and replacement
• The SIDI Heel Cup is an external, reinforced cup that stabilizes and supports the heel, with an anatomically shaped plastic design holds its form and doesn't break down over time, helping reduce heel slip and increase power transfer
• Lorica® is an exceptionally soft, supple microfiber synthetic leather possessing all of leather's positive attributes, without any of the attendant shortcomings. It is water-repellent, quick-drying, breathable and permeable to water vapor, making it an ideal material for shoe uppers. It is abrasion- and mildew-resistant, and resists stretching and deterioration from atmospheric agents
• Replaceable heel pad & heel pull tab
