Sidi's Spider SRS Loricas offer awesome power transfer and support and they're almost as comfy as your bedroom slippers. These fine shoes are made from tough, breathable Lorica for a great fit and feel and they have stiff Sidi soles that ensure all your power hits the ground. You also get Sidi's ratcheting buckles that let you dial in the fit even while riding, Sidi's High Security Velcro straps that hold fast, and their Soft Instep Closures that eliminate pressure points. These sweet shoes even have ventilated heels to keep your feet cool on hot days and Sidi's integrated rubber toe guards and SRS system that increase the life of the shoes even if you walk/run in them. Is it any wonder the Spiders are so popular with cyclocross racers?

Sidi's replaceable Spider SRS sole.

Sidi's Spider SRS soles are made of tough, reinforced nylon. They feature Sidi's exclusive Sole Replacement System replacable tread lugs, and they're drilled for toe spikes (lugs and spikes sold separately). Since the tread is replaceable, softer and more aggressive lugs can be used leading to increased traction.
In order to mount your pedal cleats to your shoes, they must have matching bolt patterns (pedals come with cleats, shoes come without). There are three configurations (diagram) used on cycling shoes, SPD-R, Look/SPD-SL and SPD. Road shoes feature one, two or even all three of these. Mountain-bike shoes usually use the SPD pattern. If you're unsure what bolt pattern your equipment uses, please contact us. We're here to help!
Sidi Soft Instep Closure System
Sidi's Soft Instep Closure System is anatomically shaped to spread pressure and provide a snug, secure, and ultra-comfortable fit.
Sidi's Caliper buckles make it super easy to fine-tune how tight your shoes are even when you're riding. Simply lift the Ratchet Levers to tighten, and press the Side Levers to loosen the fit or release the strap.
Fit Relievers are tiny cuts in the tongue that reduce bulk and keep it from rolling over and digging into your foot.
