The Ergo 2 Carbon shoes use a full carbon fiber sole that is designed for ultimate power transfer while still providing foot comfort. The breathable, and durable Lorica Microfiber uppers keep feet cool with mesh inserts. To keep the rider’s foot in place the Ergo 2s take advantage of Sidi’s Techno II buckle and ratcheting closure system to allow for fine adjustment. To prevent heel slip, Sidi employs their adjustable heel tensioning system (HSS). The Ergo 2 Carbons come in black, red or white in sizes 39-48. The Ergo 2 Carbons run $499.99.
