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 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.
Lorica is a lightweight, flexible, water repellent and breathable material made of the finest microfibers. It's amazingly durable and like leather, it improves with age.
