The Alpina ESK Pro Skate Boot has seen the highest podium more than once, and was the boot worn by the Norwegian champion, Peter Northug. Everything about this boot is designed for elite performance: it features a stiff boot flex for maximum power transfer, while the elastic calf adjustment, lacing system, and power strap offer just enough adjustability for you to customize a comfortable fit while still maintaining optimum power. The removable carbon cuff provides versatility: you can keep it on if you desire additional torsional stability, or remove it if you prefer a little more flexibility for longer courses and varying terrain. The anatomic racing footbed optimizes balance and kick efficiency and the shaped carbon and plastic heel counter minimizes movement while increasing stiffness and torsional stability. A number of features work together to keep feet comfortable. Thinsulate insulation provides breathable, low bulk warmth, and the waterproof overboot with a waterproof zipper ensures feet stay dry. The lining system and footbed materials work together to promote airflow and manage moisture so the climate inside the boot stays comfortable. The boot offers everything you need so you can go for record performance, so all that's left is for you to live up to the potential the boot is designed for you to achieve.
