The Red Dot award was given to the PRO line of models, which includes footwear for both skating and classic cross-country skiing techniques. The innovation of this line is primarily in the sole developed and manufactured by Alpina for both types of shoes. The sole for skating technique has higher cleats at the heel (compared to the sole for diagonal technique), and the cleats at the front of the sole are angled at 45 degrees to the longitudinal axis of the sole, contributing to better torsional stability in the longitudinal direction of the shoe. This sole has an insert made of a mixture of dynamically responsive plastic and carbon fibers, which further contributes to the desired maximum longitudinal stiffness and dynamic responsiveness of the shoe.

The sole for diagonal technique differs from other soles in the position of the metal axis of the sole, through which the footwear is attached to the cross-country ski binding. This axis is moved 10 mm forward, contributing to better quality push-off, as achieving contact between the ski and snow during the push-off is easier, faster, and more efficient, resulting in a stronger push-off, and the ski remaining in contact with the snow for longer during the push-off, which is crucial for diagonal technique. This axis position also shortens the glide wax zone, resulting in higher speed during downhill descents. The height of the cleats on the heel of the sole is slightly lower (compared to the sole for skating technique), and the cleats at the front of the sole are angled at 90 degrees to the longitudinal axis of the shoe, contributing to better and more friendly flexing of the shoe in the ankle area of the foot. This sole also has an insert made of a mixture of dynamically responsive plastic and carbon fibers, which further contributes

to better longitudinal stiffness and dynamic responsiveness of the shoe during push-off.
