The Bauer Vapor X400R Roller Hockey Skate is a step up from the entry-level model, supplying players with much-needed protection for the top of the foot with its integrated metatarsal guard. The quarter package utilizes the OD1N-inspired X-Ribs that deliver unbeatable support and stiffness at this price. The quarter also comes with Abrasion Guards on both sides for enhanced durability, especially outdoors. The lowers consist of a Hi-Lo Ventilator 2-Piece frame, holding Hi-Lo Court Wheels. The patented, aggressive wheel set up gives players explosive power and agility. For supreme comfort, Bauer provided the X400R skate with a moisture-wicking microfiber liner.
