Using the same anatomical design as Northwave's top tier cycling shoes, the Northwave Torpedo S. R. S. Men's Shoe delivers high levels of performance and an excellent fit, but with materials that won't empty your wallet. Its Ultralight PU upper uses a seamless design with BioMap technology to reduce nasty pressure points. BioMap takes into consideration the placement of your foot in relation to the pedal, ensuring high levels of power transfer, as well as an anatomical fit for extraordinary comfort. Add in a S. R. S. Single Ratchet System and asymmetric lower straps for a well bolstered fit, especially considering the additional heel retention system. The Carbon Light sole optimally blends carbon fiber with fiberglass. This comfort optimized blend isn't as stiff as a full blown race sole with 100% carbon, yet it retains plenty of power for hammering up hills and sprinting down straightaways. This sole is compatible with both traditional 3 hole and Speedplay cleats with the included Speedplay adapter, which features a reduced 0. 5 millimeter thickness for better energy transfer and pedal feel.
