Brooks Ghost 17 Running Shoe (Men) - Blazing Orange/Yellow 。The Brooks Ghost 17 is a neutral daily training shoe designed to offer a balanced and dependable running experience. A notable technical enhancement in this iteration is the incorporation of nitrogen-infused DNA LOFT v3 cushioning, a feature previously exclusive to Brooks\' premium models. Key Technological Features: Midsole (DNA LOFT v3): The midsole now utilizes nitrogen-injection technology to produce a foam that is lighter, more responsive, and more resilient than conventional EVA foams. This provides a balanced ride that is adequately soft for extended runs yet sufficiently firm for daily training. Refined Geometry: The Ghost 17 boasts an increased stack height for enhanced protection, while simultaneously reducing the heel-to-toe drop to 10mm (from its previous 12mm). This modification, coupled with updated flex grooves, facilitates a smoother transition from heel to toe. ​Engineered Upper: The updated double jacquard air-mesh upper has been crafted to offer exceptional breathability and a secure, effortlessly comfortable fit. Additionally, it incorporates a re-engineered kickback collar that gently curves away from the Achilles tendon to minimize any potential irritation. Outsole (RoadTack Rubber): The outsole is constructed from RoadTack HPR (High Performance Rubber), which contains recycled silica. This material is intended to deliver dependable traction on various road surfaces while maintaining its durability over extensive use.
