Take a Sidi Dominator and add a Vernice styled upper with a carbon SRS sole and you get the Spider. Depending on how you view the shoe, it's either the ultimate Dominator or a de-tuned Dragon. Either way the price reflects its great value.
The Spider SRS Carbon Mesh's upper is constructed of Sidi's proprietary Tecnomicro fabric. This synthetic fabric is thin and conforms to your foot for an exacting fit. It's also breathable, extremely stretch resistant and durable. Venting is accomplished with mesh inserts. A low profile caliper buckle and two Velcro provide precise closure. The durable Sidi Caliper buckle has a two-way ratchet for easy on-bike adjustment with incremental tightening and loosening. The adjustable Soft Instep Closure System and padded tongue eliminate pressure points. Located in the back of the shoe is a molded heel cup that helps stabilizes and support the foot. You steer from the heel, so adding this features serves up a ton of performance.
The Carbon Composite SRS Sole is super stiff for the ultimate in power to the pedal and stability over rough terrain. A small amount of flex is built into the toe area which makes the Spiders ideal for running and walking around in varied terrain. SRS (Sidi Replacement Soles) soles are easily replaceable, which means the life span of the shoe is greatly increased.
