The 20K Pump Ice Skates feature a Pro Armour IV quarter package. This quarter package has strategically reinforced embedded zones which provides superior structural support and enhanced stability. The dual-zone liner with tacky nash and durable Clarino keeps the foot dry and enhances foot lock, while the lightweight low-profile vented outsole minimizes mass, maximizes energy transfer and delivers a reactive feel. Also, the 20K Pump Skate has a pro-felt and EPE-foam hybrid tongue. The molded shape along with its foam core provides a comfortable fit and minimizes tongue twist.
