ASICS running shoes contain a lot of technologies and advanced materials, all designed to work with your feet to give you a great running experience. So here is a comprehensive ASICS running shoe anatomy, to show you what exactly makes a great running shoe.

1. Outsole

The outsole makes up the base of the running shoe. ASICS scientists have developed AHAR+ as the perfect outer sole material. It has great cushioning and grip qualities on a range of surfaces, wet or dry.

2. Space Trusstic

The Space Trusstic is a plastic bridge with a space behind it found under the arch section of the shoe. The Trusstic gives the shoe strength and stability, without sacrificing flexibility.

3. Midsole

The midsole is a layer of spongy material between the outsole and the upper. ASICS running shoes use Solyte and SpEVA as midsole materials. These cushioning materials combine bounce and durability.

4. GEL Cushioning

Cushioning materials are often added to the heel and forefoot of running shoes to help attenuate the landing shock and loading forces experienced by the body while running.

5. Lasting

The last is a layer of material which is stitched to the upper. The sockliner is placed on top of the last. ASICS shoes use Solyte and SpEVA as a lasting material. These materials have a perfect blend of cushioning and durability.

6. Sockliner

The sockliner (also called insole) is the first layer of soft foam which your foot rests on inside the running shoe. ASICS has developed sockliners made of foam which offer cushioning and make sure your foot fits comfortably inside the shoe.

7. Tongue

The tongue is a separate strip on the upper. It makes it easier to put your shoes on and take them off. It also prevents the laces from rubbing against the instep of your foot.

8. Eyelet

The eyelets are the holes the shoelaces pass through. The eyelets of a running shoe should be large enough and smooth enough so you can easily and quickly adjust your laces

9. Heel Collar

The heel collar (sometimes called heel cuff) forms the top of the shoe, supporting the heel and Achilles tendon. The collar prevents the foot from slipping inside the shoe and makes it more stable to run in.

10. Heel Counter

The heel counter is the internal plastic structure of the shoe which wraps around the heel of your foot. It holds the heel in position during the movements of running.

11. Upper

The upper is the top part of the shoe, designed to firmly hold your foot in place inside the shoe. ASICS shoes use soft, form-fitting and breathable materials in the upper.
