Designed with a Primeknit+ FORGED technology textile upper, the adidas Ultraboost Light Running Shoes deliver a premium fit. Snuggly wrapping the foot and working alongside the traditional lacing system and secure mid cage to provide a plush sock-like fit that won't slip for agile footing. The upper is made from stretchy and highly breathable fabric that contains at least 50% recycled content - allowing air to penetrate and disperse heat with a sustainable design approach in mind. The updated Light BOOST midsole features a unique molecule design to achieve the lightest BOOST foam to date. The midsole is bursting with energy and 30% lighter than previous foams to absorb impact shocks and return explosive energy while working alongside the LEP (Linear Energy Push) Torsion System for a flexible, supportive and smooth ride. Finished with a lightweight Continental™ Rubber outsole for flexible traction on all kinds of surfaces in both wet and dry conditions.
