Like all Heelside's offerings, the Combo combines solid features&top performance at a low budget price. Combine that with the fact that we purchased these bindings on closeout&are offering a killer deal, and you can't go wrong with the Combo from Heelside. The Combo is a step up from the Unibody in that it has an aluminum heelcup&aluminum quick release buckles that will last longer than their plastic counterparts. Combine that with a nice padded quick adjust hi-back, integrated base pads for shock absorption&you can't blame the bindings for any bad days this winter.Features4x4 compatibleLight nylon base with adjustable 6061 aluminum heelcupAluminum quick release bucklesEVA padded highback with tool-less forward leanSuper plush molded EVA strapsRubber baseplate pads for superior shock absorptionIntegrated toe ramp improves responsiveness and reduces toe dragAvailable in sizes: M/L(9-12) L/XL (10-14)
