GEL-KINSEI 4

Under the hood

• Guidance Line

  Guidance Line places a visible groove in the mid and outsole that follows the foot's center of pressure from heel to toe. The result is a more adaptive running platform, creating a smoother transition from heel strike to toe-off with each stride. The Guidance Line thus helps runners to maintain a natural, efficient gait, especially over long distances.

• Propulsion Trusstic

  Plastic bridge under the arch which mimics the connective tissue in the foot by creating tension as the foot moves through each step.

• 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.

• AHAR (ASICS High Abrasion Resistant rubber)

  Tough material placed in critical areas of heavy contact on the shoe for exceptional durability.

• Space Trusstic System

  Plastic bridge under the arch creating a pocket between it and the midsole which improves flexibility and gives the shoe strength and stability.

• Heel Clutching System

  Lightweight heel counter on the outside of the upper which provides improved support and fitting around the heel.

• I.G.S. (Impact Guidance System)

  The Impact Guidance System (I.G.S.) is an ASICS design philosophy. It aims to make shoe components from rear to midfoot and forefoot to work together effectively to allow the body to perform in a natural manner. ASICS designers strive to compliment, not correct, how the legs and feet move.

The result is a more adaptive running platform, creating a smoother transition from heel strike to toe-off with each stride. The Guidance Line thus helps runners to maintain a natural, efficient gait, especially over long distances.

• Personal Heel Fit (P.H.F.)

  Memory foam lining the heel collar and tongue creating a personalised fit around the ankle.

• 3M Reflectivity

  Special reflective material which enhances visibility in poor light. 3m Scotchlite is a registered trademark of the 3M Company.

• Propulsion Plate

  Plate in the sole which provides stability in the forefoot and offers flexibility for additional comfort.

• DuraSponge

  DuraSponge is a blown AHAR compound for enhanced cushioning and durability in the forefoot. ASICS High Abrasion Resistance Rubber (AHAR) is a tough compound used at the heavy contact area of the outsole.
