About Sidi Women's Alba 2 Road Cycling Shoes

The Politex material is constructed of several overlapping layers with different physical and mechanical properties. This compacted PVC is then coupled to two fabrics (knitted fabric and felt) that is then film dyed for long lasting color retention. Politex offers strong resistance to rips, lacerations, stretching and fading. Politex is made in strict compliance with European regulations and is considered a "green” product. The MILLENIUM 4 CARBON COMPOSITE SOLE is injected molded carbon fiber in a matrix of nylon that creates a significantly lighter and stiffer sole that is less susceptible to changes because of aging or prolonged usage. The SOFT INSTEP 3 CLOSURE SYSTEM is a wide, anatomically curved strap combined with a soft, thermo-formed EVA pad that distributes pressure evenly over the instep area. The SOFT INSTEP CLOSURE SYSTEM is adjustable from both sides, to perfectly center the EVA pad over a high or low instep. The system eliminates the need for the High Instep Extender. The SOFT INSTEP CLOSURE SYSTEM is replaceable. 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 customized 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. Reinforced heel cup. Replaceable heel pad. New Model
