The Lotto Raptor 100 Speed is the new and improved update to the Raptor line of shoes with more cushioning and durability than ever! The Multilayer Kurim upper allows the shoe to be stable without adding weight, and molds to your foot for a fast-feeling fit. Underfoot, the new Hyperpulse system, made from a mix of EVA and ETPU with a unique blade design, provides excellent cushioning and comfort targeting specific areas of the feet, focusing on shock absorption and energy return to keep you at your best throughout the match. Lotto also introduces the first Vibram outsole on a tennis court! This updated material has incredible traction and durability on the outsole, and is 30% more wear resistant than other tennis shoes on clay courts.
