It is specifically engineered for highperformance, high-mileage cyclists, with tremendous stiffness for maximum power transfer and some controlled flex in the toe area that relieves stress on the plantar tendon and helps promote circulation. The Carbon Lite SoleÆ is handmade exclusively of sheets of T700 carbon fiber in a 3k weave pattern, laid up at opposing angles that maximize resistance to mechanical stress and allows for a slight amount of controlled flex in the toe. The Carbon Lite SoleÆ is compatible 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 EyeletÆ for easy cleat alignment and replacement. Techno II BuckleÆ SIDIís Techno II BuckleÆ provides even pressure distribution with fine-tooth ratchet adjustment of monofilament line tension, for ultra-smooth adjustment that helps the shoeís upper conform to the shape of the foot for a customized fit. Like most SIDI small parts, the Techno II BuckleÆ is user-serviceable and replaceable. Adjustable Heel Security SystemÆ (HSS) The Adjustable HSSÆ reinforces the top of the heel cup, adjusting to securely close the back of the shoe around the heel above the calcaneus (heel bone). The Adjustable HSSÆ allows 6 mm of lateral adjustment on either side for optimized fit, improving power transfer and comfort by eliminating heel lift. The Adjustable HSSÆ is replaceable, and may be retrofitted to some 2007-2009 SIDI models featuring SIDIís Heel Security SystemÆ. The Adjustable HSSÆ is exclusive to SIDI cycling shoes. Caliper Buckle In 1989, SIDI introduced the first ratcheting buckle closure for cycling shoes. The rest is history. The Caliper Buckle allows precise, incremental tightening and loosening of the closure, for easy on-the-fly microadjustment. Pulling upward on the lower lever tightens the strap, click by click; pressing down on the upper lever loosens it a step at a time; an outward pull on both side levers completely releases the buckle. The Caliper Buckle is user replaceable, and may be retrofitted to many earlier SIDI models with the addition of the matching Caliper Strap. High Security VelcroÆ In 2002 SIDI introduced High Security VelcroÆ (globally patented). High Security VelcroÆ integrates interlocking polymer teeth into the straps that engage when the strap is closed, for a more secure, slip-free closure and dramatically increased useful life of the VelcroÆ strap. Today High Security VelcroÆ remains an exclusive feature of SIDI cycling shoes. SIDI Heel Cup Inspired by SIDI motorcycle boot technology, the SIDI Heel Cup is an external, reinforced cup that stabilizes and supports the heel. The sturdy, anatomically shaped plastic design keeps its shape and doesnít break down over time, helping reduce heel slip while improving power transfer. The SIDI Heel Cup also provides additional foot protection in the event of a crash. SIDI Dual-Density Insoles SIDI Dual-Density Insoles provide better foot support for improved comfort and performance, with a soft-durometer pad under the ball of the foot that dissipates pressure, reducing hotspots and improving vibration damping. The footbedís felt finish improves moisture management and heat dissipation.
