The Wilson Men`s Rush Pro Ace Wide Tennis Shoes continue the strong tradition of the Rush Pro 3.0 and 3.5. The Ace has the same outsole as the above-mentioned models, and the upper is constructed of a breathable mesh, which offers strong ventilation and support. To enhance the shoe`s stability, Wilson added the 4D Support Chassis and to cushion and protect the heel, they incorporated the RDST + EVA construction. The RP Ace is the perfect shoe for a recreational tennis or pickleball player. Compared with the Rush Pro 4.0, the Ace has a more spacious toe box. Upper: Constructed of breathable mesh, the upper balances breathability with support. Midsole: R-DST+ utilizes highly compressed EVA material for dynamic cushioning and rebound. The 4D Support Chassis is an asymmetrical, heel-to-toe chassis that delivers enhanced stability, and limits supination and torsion. This helps players control pivot movements while setting up for powerful strokes. Outsole: The all-court Duralast outsole provides excellent durability and traction. Designed for hard court usage. Color: Black and Ombre Blue
