INTRODUCTION

The DS Skyspeed is a moderate feature, moderate neutral shoe designed for speedwork, racing and daily training. It is built with a semi-curved shape.

CUSHIONING

Rearfoot Gel cushioning system is a large silicone based gel that attenuates shock during impact.
Forefoot Gel cushioning system is a silicone based gel that attenuates shock during toe-off.
Impact Guidance System (IGS) is utilized in the lateral heel to further decouple the shock of the heelstrike.

MIDSOLE

Space Trusstic System is located at the bottom of the midsole and is made out of thermal plastic. This gender specific midfoot unit controls midsole deformation which allows for natural foot movement while stabilizing the midfoot of the shoe.
Impact Guidance System (IGS) is Asics' design philosophy that enhances the foot's natural gait.
Guidance Line is a vertical flex groove component of IGS and is primarily articulated in the forefoot to improve gait efficiency.

UPPER

California Slip Lasting involves stitching the upper along the perimeter of a synthetic material which is then attached to the midsole.
ComforDry Sockliner is made from an anti-bacterial material that not only reduces odor and moisture but also provides additional cushioning.
Discrete Eyelets are independently placed to disburse lace tension and are designed to enhance comfort.
Biomorphic Fit Upper is a stretch material located in the forefoot which moves with the foot to reduce the potential for irritation.
Asymmetrical Lacing Design better follows the shape of the foot for an improved fit experience.

OUTSOLE

Asics High Abrasion Rubber (AHAR) is located in the heel and is a carbon rubber that offers exceptional durability.
