The XTP (extreme thermal protection) is a special footbed with superior thermal insulation. The XTP footbed is made from a combination of a highly isolative felt material and a memory foam layer for superb underfoot comfort.
- XTP can be found in our Expedition and Mountaineering boots where it helps to protect against extreme cold.
- The base of footbed is made from felt and anti-static 3 mm Memory Foam.
- The top layer is insulated with Thinsulate for warmth with highly wicking Coolmax to transport moisture away from the foot.
