Professional performance for ambitious players – uncompromisingly lightweight, precise, and optimized for indoor hockey. The GRAF Supra 515X inline skate is based on the proven SUPRA hockey boot and combines decades of experience with state-of-the-art materials. The 3D Composite Quarter construction molds precisely to the individual foot shape, enabling direct, lossless power transfer with every step. The side panels made of SRPP (Self-Reinforced Polypropylene) set new standards: This advanced composite material is up to 50% lighter than carbon fiber – while offering three times the impact resistance of conventional fiberglass-reinforced plastics. The result is a boot that withstands impacts and intense play without adding unnecessary weight. The microfiber lining actively wicks moisture away, keeping the foot dry and preventing chafing, even during long training sessions. The QuickTurn 45 aluminum chassis transfers acceleration and cornering energy directly to the QT 3.0 Dual Layer Indoor wheels, whose hard core delivers maximum rebound while the grippy outer layer guarantees precise grip on indoor surfaces.
