The Magnum Heavy Duty Foot and Magnum Heavy Duty System is designed for amputees weighing up to 350 pounds (160 kg). Both the Magnum System and the Magnum Foot have proven to be very durable and reliable, while providing excellent response for amputees. Backed by extensive laboratory testing prior to its introduction, the Magnum Heavy Duty System, designed for transtibial amputees, has proven to far exceed the strict testing standards set by ISO 10328. The foot and system are both remarkably lightweight, and the slim design and lifelike cosmesis offer a more pleasing appearance. Both men’s and women’s versions of the Magnum Foot are available. The foot is available separately or as part of three different heavy duty systems. The Magnum Heavy Duty (HD) System was created to stand up to the pressures of higher weights. It is a complete socket-to-foot solution designed for a user weight limit up to 350 pounds (160 kg).The Magnum Heavy Duty System is available in three toe resistances and two heel heights.
