The dense rubbered sole in SIDI's Turbo Mountain Bike Shoe provides plenty of traction which is great for touring, bikepacking and backcountry rides. SIDI's MTB Outdoor sole has large lugs and tread that's hikeable on lose terrain and it sheds mud quickly. After you've crossed a muddy pathway on foot, you can hop back on your bike and clip your Turbo shoe back into the pedal without any interference of mud clogging the cleats. The midsole has enough stiffness to support your foot in the pedal, yet it allows the heel and toe to flex so you can dismount and walk comfortably. The new Turbo shoes are versatile. The MTB shoe features 4-bolt SPD-compatible inserts, or a bolt-on tread insert for flat pedals. For a comfortable fit, dial SIDI's Techno-3 system until you feel just the right tension. The Wiring creates even pressure across the upper, so it fits the exact shape of your foot. The reinforced heel cup keeps the foot from sliding, and it protects in case of crash. The SIDI turbo is not for fast rides, it's best for long distance adventures in and out of the saddle. The structure handles the duress of long distances while protecting and providing support for the foot as you explore natural terrain with your off-road bike.
