The Asics Gel Resolution X takes stability, durability, and comfort to the next tier as Asics incorporates key updates, and builds upon the popularity of the previous generation (Asics Gel Resolution 9). A re-engineered Dynawall maximizes the lateral stability, while maintaining comfort as you plant and cut aggressively for changes in direction. The midsole is now more plush than previous versions with a combination of FlyteFoam Blast+ and ECO Foam; forget not the signature Gel cushioning in the forefoot. The medial side of the ankle collar has been raised to provide comfortable padding, while the PGUARD on the medial side of the toe box provides drag protection, for those players who slide on hard courts. A Full length AHAR Plus rubber outsole carries on the reputation of being one of the most durable in the industry, and the tread pattern provides good grip on a variety of surfaces. Backed by a Tennis Warehouse six month outsole durability guarantee.
