The Asics Gel Kinsei 4 is Asics most sophisticated running shoe, using slim lined and stronger materials for a lightweight but well supported shoe with engineered components delivering improved comfort, fit and performance for an adaptive platform to enhance natural gait efficiency. This is an instant classic for serious runners.

The Impact Guidance System enhances the foot's natural gait from heel strike to toe-off improving the efficiency and comfort of your foot-strike and movement. With Guidance Line technology a vertical flex groove decouples the tooling along the line of progression for enhanced gait efficiency.

The Heel Clutching System features an Exoskeletal heel counter to provide improved support and create an improved heel fitting environment. The Discrete Heel Unit takes the Impact Guidance System to a new level by creating the highest degree of shock attenuation and stability.

The Propulsion Trusstic mimics connective tissue in the foot by creating tension as the foot enters propulsion stage whilst asymmetrical lacing creates an anatomically correct lacing environment that reduces potential for irritation and provides improved comfort and fit.

The Cuprothermo metallic film in the upper retains heat in cold weather and releases heat in warm weather making an adaptable shoe that will help you in all weather conditions. AHAR stands for High Abrasion Rubber, placed in critical areas of the outsole for exceptional durability.

A Personal Heel Fit comes courtesy from the memory foam lining in the heel collar and tongue for a personalised fit around the ankle, while Biomorphic fit in the upper utilises stretchy material to reduce bunching, which can lead to blisters and irritation, when the shoe moves. This comfort is also enhanced by the discrete eyelets which disburse lace tension and improve the overall fit.

With an X-40 ComforDry Sockliner, as well as the rearfoot GEL cushioning systems, there is an exceptional level of comfort provided by these shoes.
