Free/Lock 2.0 ski-to-walk mechanism and Frictionless Pivot deliver unbeatable uphill performance. Complete Tech inserts in the toe and heel allow for maximum binding compatibility. The 120 model has a slightly softer plastic construction than the Hawx Ultra XTD 130 CT GW model but offers the same highly customizable Mimic Platinum liner to exactly match your foot shape. The Touring Flex Zone adds even more comfort and a GripWalk sole offers walking comfort with no sacrifices to on-snow performance. All mountains, one boot!
