Asics Gel Kayano 18

Technical Specification I.G.S. (IMPACT GUIDANCE SYSTEM) - ASICS design philosophy in which the individual components of the shoe work together resulting in a more comfortable step and an improved gait. REARFOOT AND FOREFOOT GEL CUSHIONING SYSTEMS - Silicone-based material placed in critical areas of the sole which dampens shock when the foot hits the ground allowing for a smooth movement through the step and reducing the risk of injury. COMFORDRY SOCKLINER - Insole placed inside the shoe which provides cushioning keeping the foot drier and cooler. FULL LENGTH GUIDANCE LINE - Vertical flex groove in the sole running from heel to toe which encourages a more efficient running style. SOLYTE MIDSOLE MATERIAL - Spongy layer between the sole and upper designed to absorb shock and cushion the foot. Solyte is a lighter material than SpEVA and EVA and features enhanced durability. DUOMAX SUPPORT SYSTEM - Dual density midsole material positioned sport specifically which enhances support and stability. DISCRETE EYELETS - Independently placed eyelets where the laces pass through the upper which disburse lace tension improving fit and reducing possible irritation. ASYMMETRICAL LACING DESIGN - Lacing which follows the natural curve of the foot giving a better fit and reducing the potential for irritation.
