The Rollerblade NJ Pro Skates are firmly on the top shelf of Rollerblade’s Street Line. The boots are firmer, especially around the forefoot and toe. This rigidity better responds to the skater’s demands and transfers power to the wheels. Blank™ Premium Liners are freaks. Blank Liners are known for being walkable and comfortable on their own when removed from the boot, but these take it to the next level with a double padded tongue, laces and a full rubber sole with heel lift that not only makes them walk better, but absorb shock better.
