Dual Core Technology – A new "Power Injection" method allows Lange to inject two different durometers of plastic simultaneously through 5 injection ports, with the two plastics being directed to specific parts of the boot. The harder plastic goes to the heel, spine and lower shell to retain stiffness, while the softer plastic goes to areas that wrap the foot and lower leg for comfort.
