The Alpina BC 1550 boots are a great backcountry touring boot. The strong and rigid multifunctional heel counter accommodates various types of heels, provides strong support, and prevents the in and out movement that causes painful blisters. The Heel counter also highly improves the torsional stability of the shoe sole. A special, anatomically designed footbed composed of three different materials assures a perfect fit and even distribution of force. Finally, the Thinsulate insulation system provides insulation, breathability and snow-proofing to keep your feet warm and dry.
