Asics SS12 Gel Kinsei 4 Mens Running Shoes

The GEL-KINSEI 4 features many ASICS advanced technologies to make it a truly brilliant update to ASICS most sophisticated running shoe. The GEL-KINSEI 4 uses slimline materials for weight reduction and stronger materials for added structure and support. Redesigned and re-engineered components improve comfort, fit and performance so that the GEL-KINSEI 4 provides a lighter, stronger more comfortable adaptive platform to enhance natural gait efficiency. A discrete heel unit provides improved support and takes the Impact Guidance System (IGS) to a new level by creating our highest degree of shock attenuation and stability. AHAR+, a thinner and lighter version of ASICS High Abrasion Resistant rubber, features in heavy contact areas of the outsole to reduce excessive wear. For maximum comfort, Cuprothermo,...

The GEL-KINSEI 4 features many ASICS advanced technologies to make it a truly brilliant update to ASICS most sophisticated running shoe. The GEL-KINSEI 4 uses slimline materials for weight reduction and stronger materials for added structure and support. Redesigned and re-engineered components improve comfort, fit and performance so that the GEL-KINSEI 4 provides a lighter, stronger more comfortable adaptive platform to enhance natural gait efficiency. A discrete heel unit provides improved support and takes the Impact Guidance System (IGS) to a new level by creating our highest degree of shock attenuation and stability. AHAR+, a thinner and lighter version of ASICS High Abrasion Resistant rubber, features in heavy contact areas of the outsole to reduce excessive wear. For maximum comfort, Cuprothermo, a metallic film, is used in the upper to retain heat in cold weather and release heat in warm weather, while X-40 ComforDry Sockliner gives cushioning and anti-microbial properties for a cooler, drier, healthier environment.

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.
FULL LENGTH GUIDANCE LINE - Vertical flex groove in the sole running from heel to toe which encourages a more efficient running style.
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.
HEEL CLUTCHING SYSTEM - Lightweight heel counter on the outside of the upper which provides improved support and fitting around the heel.
DISCRETE HEEL UNIT - Dual density GEL Cushioning in the heel which provides an improved level of shock dampening and stability within the shoe.
PROPULSION TRUSSTIC SYSTEM - Plastic bridge under the arch which mimics the connective tissue in the foot by creating tension as the foot moves through each step.
ASYMMETRICAL LACING DESIGN - Lacing which follows the natural curve of the foot giving a better fit and reducing the potential for irritation.
CUPROTHERMO - Metallic film in the upper which retains heat in cold weather and releases heat in warm weather.
BIOMORPHIC FIT UPPER - Stretchy material strategically placed on the upper which reduces bunching when the shoe moves reducing the risk of blisters and irritation.
