The new Adidas Ace II Mens Tennis Shoe is a huge improvement from its predecessor by offering a new Micro-Fit to give all feet sizes a comfortable fit without sacrificing weight and cushioning. While being low to the ground, the Adidas adizero Ace II uses its adiWEAR technology on the outsole to provide great durability. On the midsole, youll find Adidas adiPRENE that was constructed with comfort and cushioning in mind and this is all backed by the Torsion system that Adidas incorporates in most of their shoes which give outstanding stability.
