In the United States, 71 percent of dysvascular amputations are below-knee amputations. Hiking can build muscle strength and combat stress and anxiety. Hierex is a hiking prosthetic leg for below-knee amputees. It applies a water cooling system that reduces sweating, allowing the user to hike for a longer distance. Amputee hikers also have a difficult time with uneven terrain on the trail—causing pressure up to the limb and creating pain. The prosthetic foot on Hierex provides better shock absorption than hiking shoes. The sole enhances stability and the entire base replaces the hiking boot.Designed by: Kesu WangContact: Kesu Wang
