Just like models of the past, the Reebok 28K skate features Reebok's SkateLock and Pump technologies to ensure a comfortable fit that is right out of the box! However, something new for this line of skates is a narrower, slimmer fit through the heel and forefoot. Reebok designed their Ribcor line of skates to cater to the quick, agile skater, who lives in tight spaces. As for the lower portion of the skate, the Ribcor 28K features Reebok's newest holder, the SpeedBlade 4.0 holder. This holder sits 4mm higher than previous holders, giving the player a tight, aggressive turning radius!
