Hammer it out

Cyclocross is slippery and muddy. Shoes need to engage quickly into the pedals and provide optimal power transfer while also being flexible enough to run in. The Northwave Hammer CX MTB Shoes are designed using BioMap technology so that you'll never think about your feet while racing again. 

In the same manner as Northwave's top-of-the-line shoes, the uppers of the Hammer have been designed using BioMap technology. The result is a seamless upper from an ultralight polyurethane that minimizes chafing and hot spots. Because the uppers are seamless, this allows Northwave to use an internal, Integrated Heel System to lock your foot into the shoe. This minimal system shaves weight by eliminating the need for an external heel cup. The footbed is Northwave's EVA and microfiber Performance Pro which supports your foot for long hours pedaling. To keep your feet dry, a neoprene sock was integrated into the liner to create a sock that hugs your ankle. The shoes are secured to your feet with three hook and loop straps.

Northwave's Speedlight 3D CX Sole is a nylon chassis that has been injected with fiberglass. Although it is not as stiff as a full carbon fiber sole, nylon is ideal for mountain biking and cyclocross where you many find yourself walking a bit. Extremely stiff-soled shoes may cause blisters and don't provide needed grip on the ground. This sole was specifically designed for cyclocross with grip along the medial zone as well as the possibility of adding front studs for muddy, rainy weather.

The Northwave Hammer CX MTB Shoe - Men's come in whole sizes 38.0, 39.0, and 47.0. They are available in whole and half sizes from 39.5 to 46.5. They have been designed in two colors: Matte black and Red/white/green.

  • Ultralight PU upper

  • Three hook-and-loop straps

Nice Shoes don't trust size chart

    These are nice shoes but don't trust the size chart. I wear a size 12 and the sizing chart on this page recommended a size 45 which was a bit too small...should have been a standard 46 which is a typical equivalent for size 12
