The Reebok Instapump Fury X GTX ‘Infinium’ delivers a rugged weather-resistant interpretation of the iconic Instapump Fury. A monochrome black finish is applied to the ballistic mesh upper, lined in waterproof Gore-Tex and equipped with a zippered sheath. Interior bootie construction, coupled with Reebok’s retro Pump technology, provides a snug, comfortable fit. The slip-on rides on a decoupled EVA midsole, enhanced with a TPU midfoot plate and supported by a lugged rubber outsole.
