Asics GT-1000 4 Light Blue/Black

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

Forefoot GEL
ASICS GEL is a shock absorption system that uses silicone to satisfy the needs of both amateurs and professional athletes. Forefoot GEL reduces the force of the load during push, increasing performance and drastically reducing the risk of injury.

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.

I.G.S.
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.

Rearfoot GEL
ASICS GEL is a shock absorption system that uses silicone to satisfy the needs of amateurs and professional athletes alike. Rearfoot GEL offers omni-directional shock absorption, it not only absorbs harmful shock, but helps to stabilize impact forces on the heel.

SpEVA
SpEVA is an exclusive Asics midsole material that optimizes the "compression and rebound" phenomenon, reducing the flattening of the midsole.

AHAR+
A thiner and lighter version of AHAR, but with the same resistant effects, the AHAR+ rubber is placed strategically over the outsole to improve strenght and reduce excessive wear.

Dynamic Duomax
Dynamic DuoMax Support System is a dual density midsole with a softer top layer for more sensory feedback and added comfort.
