The Lotto Vector V offers exceptional all-around comfort and performance. Lotto has upgraded the materials in the upper to make it more breathable and supportive than ever. The shoe still features Lotto's unique ReactiveArch technology, a concave-shaped outsole that moves naturally with your foot as it strikes the ground, providing exceptional energy return and stability. Also, the Syn-Pulse midsole utilizes an elliptical frame to help propel your foot off the court on impact for explosive movements. The improved outsole offers even more durability and traction, and is backed by a 6 month outsole durability guarantee. These shoes also come with two sets of laces so you can find your favorite look.
