Item # SID003I

Breezy and easy on the feet.

With their proven closure system and upper venting design, the Sidi Spider SRS Mesh Shoes are back with a new sole composition and the sheer elegance that you've come to expect from the Italian shoemaker. And like all Sidi shoes, the Spider SRS Mesh Shoes were designed to provide you with years of trouble-free use, relying on an extensive range of replaceable components to ensure that your investment lasts.

Starting with the closure system, your foot is held in place by Sidi's stiff heel cup and its tried-and-true, two-way ratcheting Caliper Buckle. Assuredly, you've seen the Caliper Buckle imitated by lesser shoemakers. This design, however, was invented by Sidi decades ago. The system allows for incremental adjustments, either pre-ride or on-the-fly, and it's further complemented by Sidi's take on two hook-and-loop straps. Not your standard Velcro, these two volume-controlling straps feature Sidi's patented High Security Velcro. So, you'll never experience any fraying, wear, or loosening of the Velcro over any period of time. Together, as a system, the three-point closure system ensures that you get the perfect fit every single time that you buckle up for a ride. And for those who prefer as tight a fit as possible, the shoe's tongue and instep strap have both been padded generously to allow for supreme comfort with tight buckles.

For a difference that you'll feel on the first pedal stroke, Sidi gave the Spider SRS an all new Carbon Composite SRS Sole. This sole not only shaves 80 grams per pair over the previous version, but it also achieves equilibrium between comfort, efficiency, and durability. The sole is plenty stiff for riding, but not so stiff that you can't scramble in them with a bike on your back. The rubber lugs are softer than those on the Dominator 5, so they grip rock better in both wet and dry conditions. And because they're softer, they wear a bit more quickly, but wearing down the lugs isn't an issue because they're bolted on to the sole as part of Sidi's Sole Replacement System (SRS). Sidi has also added a rubber toe guard in front for greater durability.

With a degree of engineered flex in the new Carbon Composite SRS Sole and a secure and slip-free heel, you won't have to worry about hot spots. And you don't have to worry about heat in the rest of your feet, either, with the Spider's combination of Technomicro microfiber and cooling mesh panels — giving you comfort, fit, ultimate ventilation, and durability.

The Sidi Spider SRS Mesh Shoes are available in whole and half sizes from 40.0 to 48.0 and in the color White/black/red vernice. Please note that these shoes are intended for use with two-hole mountain bike cleats.
