The Lange RX 80 W is a great ski boot for the strong intermediate to advanced skier who is looking for a medium to narrow forefoot and medium to narrow shaft of the leg. Lange's Dual Core Construction uses a combination of softer and harder plastics in the shell to create a powerful and smooth flex with a high amount of energy transfer. The new Shin Control padding in the liner uses asymmetrical padding to keep your legs comfortable and a more even distribution of pressure as you flex into your boots. The Dual 3D Sport Liner has anatomically correct padding in all of the right places to keep your foot supported, and Thinsulate Insulation adds extra warmth. If you are a strong skier looking for a smooth flexing and supportive boot, the Lange RX 80 W is a great choice.
