Light on weight but heavy on innovation, the all-new GEL-Lyte33 2 Running Shoe boasts F.A.S.T. innovations and ASIC's new breakthrough technology for improved speed and flexibility. Designed to give underpronators to neutral runners a totally new speedy experience, the GEL-Lyte33 2 features FluidAxis technology for lightweight flexibility and a responsive ride. F.A.S.T. Drop yields a 6mm heel-to-toe height differential which encourages faster running. The F.A.S.T. Heel comfortably hugs the heel to provide a secure fit while minimizing secure weight. The F.A.S.T. Sole uses less rubber on the outsole to help increase speed by reducing weight, all while providing added durability in key locations. F.A.S.T. Ride enhances platform feel and increases responsiveness with a slightly firmer midsole that's built for speed. The asymmetrical, dual-density midsole aids re-supination at toe-off, with a softer SpEVA layer providing bouncy underfoot comfort atop a firmer, more responsive Solyte base. The Guidance Line vertical flex groove decouples the tooling along the line of progression for enhanced gait efficiency. The Rearfoot GEL Cushioning System attenuates shock during impact and toe-off phases, and allows movement on multiple planes as the foot transitions through the gait cycle. ASICS High-Abrasion Rubber (AHAR) is placed in critical areas of the outsole for exceptional durability. Lace-up design. Medium width. Imported.
