The Northwave Extreme XC MTB Shoes have achieved many great results, thanks to the Northwave athletes who have always appreciated the lightness (just 312 g), the construction of the unidirectional carbon outsole that allows to “unload to the ground” all the power and, again, the possibility of a millimetric fit thanks to the X-Frame 2® upper construction and the 2 SLW3 dials.
