The heart of the K10 is the Leafspring Flex Bar which maintains the flexibility of the footwear whilst adding traction. It is constructed from ultra-thin multiple layers of hardened stainless steel that reduces stress & provides an even “normal” flex that will last a lifetime. The independent front & rear binding system has been vastly enhanced this year & allows users to easily set the size required & then use the quick release bindings for fast attachment & removal. Ten 19mm spikes provide traction & the two sections of the K10 slide together along the Leafspring bar to reduce their pack size. These brilliant lightweight crampons are supplied with a set of Snow Release Skins. These durable & lightweight reinforced neoprene skins stop snow from balling up under the K10 especially in mushy snow conditions.
