Sidi Dominator 7 Mega Mountain Bike Shoe: Sidi has redefined their best selling MTB shoe. Picking up where the Dominator 5 left off, this new design brings together European handcrafted quality, a performance oriented fit, and bulletproof durability. Sidi's Competition lugged MTB sole is made from nylon for extended wear resistance, rigid performance and excellent traction on a variety of surfaces. The upper is done in Lorica, a supple yet strong synthetic material. Strategically placed mesh inserts provide extra comfort in warm conditions.
