It is manufactured using the "Water-Tech" water treatment. Lower environmental impact, less noxious emissions into the air and into the work environment and the fact that not solvents, but water-based products were used, is beneficial to the environment as well as the final user Gore-Tex®: The Gore-Tex® membrane is at the heart of all products engineered with Gore-Tex® fabrics. It contains over 1.4 billion microscopic pores per square cm (9 billion pores per square inch). These pores are 20,000 times smaller than a water droplet, but 700 times larger than a water vapour molecule. Water from the outside will never penetrate. Yet perspiration can escape easily, so that less moisture is trapped in the insulation. The result: you stay warmer when it’s cold and drier when you perspire Tecno-3 System 3: Sidi's Techno-3 System dials in fit along the entire length of the shoe, adapting the upper to the shape of the foot for a customised fit. Sidi’s famously reliable and replaceable closures are improved by an all new proprietary Sidi Wire material that is completely non-binding for intuitive and effortless on-the-fly adjustments. Like most Sidi small parts, the Tecno-3 Buckle is serviceable and replaceable Sidi Heel Cup: Reinforced cup that stabilises and supports the heel. Anatomically shaped plastic, reduces heel slip and provides increased power transfer. Provides additional foot protection in the event of a crash Replaceable Heel Pad: For walkability, Sidi cycling shoes include a replaceable polyurethane heel pad Buy Sidi Footwear from Chain Reaction Cycles, the World's Largest Online Bike Store.
