The much-anticipated evolution of the VIPER is here, the VIPER XL, featuring a wide range of material, construction and design enhancements. Its redesigned upper sports breathable sandwich mesh and stylish brushed metallic PU. The upper rides on a full length EVA midsole that cushions the forefoot, and a nine-spike cleat configuration with optimized placement and variable lengths to boost lateral quicks and acceleration. The VIPER XL has been ruggedized with high abrasion toe material on the bumper, performance action leather, and reinforced eyelet support. An O-ZONE sockliner and insole provides odor and fungal protection. The VIPER XL is one of 3N2's most popular pro-grade spikes, worn by a number of Major Leaguers, including Ryan Braun, AJ Burnett, and Chris Perez.
