Reebok 20K Pump Hockey Skates Regular Width Size 4 (Used)

My son wore these skates for about a year. Reebok's 20K skates are built with Pro line craftsmanship. The Dynamic Support System solidifies the skates and controls flexion while working with reinforced composite quarter package to maximize the energy transmission in every stride. Continuing to build on the Pump franchise, the 20K skates provide the best out of the box fit, customization and performance. Dynamic Support- The Dynamic Support System optimizes flexibility and stiffness to effectively maximize the transmission of human power. This is found in the Spinal zone, where wrapped fibers oriented at 90° and 0° supports and locks the heel in place. It is also found in the flexion zone where composite fibers are at a 45° angle to enhance the flexion profile of the skater. Power Transmission- Metal mesh reinforced. Structurally enhanced to provide increased power transmission and added protection. Fit Accuracy- The Pump works by eliminating natural gaps around the ankle, giving you a customized fit while preventing heel lift. Agility- Designed to provide a greater range of motion, the back tendon guard and Pro skate tongue bring superior agility on the ice.
