The Bauer Pro Tall hockey skate socks are a blend of 61% nylon, 37% polyester and 2% Spandex that gives you a compression type fit and breathability. Fitting just below the knee, the socks use the Sanitized technology that helps prevent bacteria growth by helping wick moisture away from your foot. The double wall construction at the top of the foot helps eliminate lace bite and improves fit. The unique Y shaped seam construction ensures a better fit and eliminates sock bunching inside the skates.
