Adidas Ultraboost Vs. Asics Gel Kayano – A head to head comparison

In the above sections, we have covered a brief overview and some major differences between Asics Gel Kayano and Adidas Ultra boost.

In the following sections, we have provided you with an in-depth analysis of these two running shoes.

Outsole

The outsole of Adidas Ultraboost is made by having Continental rubber placed strategically on the outsole. In this version, this is a big change to the outsole.

In the previous models, there was an almost continuous layer of Continental rubber. However, if you observe, you will find that in this version this rubber is placed only at the tip of the forefoot and at the central part of the forefoot.

However, that didn’t change the gripping capacity of this shoe and you will get a comfortable and stable ride.

The outsole of Asics Gel-Kayano is made from AHAR or Asics High Abrasion Rubber. This is a long-lasting and durable rubber and will provide you with an excellent grip on dry and wet surfaces.

This is flexible rubber and will not add rigidity to the sole. To make this shoe more flexible there are grooves in the forefoot. This improves flexibility and also makes the heel-to-toe transition easier.

Midsole

The midsole of Adidas Ultra boost has boost cushioning. In fact, this version of Ultra boost has more boost to provide you with an ultimate cushioning experience.

It provides you with a soft and comfortable underfoot feeling and providing you with a balance of softness and responsiveness.

It has the LEP Torsion System. This provides you with rigidity and propulsion to the forefoot.

In this version also, the heel-to-toe drop is 10mm. This makes this running shoe a great option for people suffering from problems like Achilles Tendonitis.

The midsole of Asics Gel Kayano is made from Flytefoam Blast. This is a lightweight and durable material that provides you with responsive and balanced cushioning. Also, this material is environmentally friendly.

It has the forefoot and rearfoot gel cushioning system and this silicone-based gel system provides you with responsive shock absorption.

It also has the Dynamic DuoMax Support System. This helps you by controlling your pronation. Also, since it controls the movement of your feet, it provides you with a smoother heel-to-toe transition.

It has the Space Trusstic. This reduces the weight of the sole and provides you with stability and it also retains the structural integrity of the shoe.

Also, it has the Gender-Specific Trusstic. This is fine-tuned to the biomechanical needs of the men’s and women’s feet and provides them with protection and a smooth ride.

The I.G.S or the Impact Guidance System creates a smooth and balanced heel-to-toe transition.

Upper

The upper of Adidas Ultraboost is made from Primeblue. It is a high-performance upper that is made from recycled materials.

This upper material is lightweight and will not add to the bulk of this shoe. Also, it will provide you with a comfortable and secured fit. Also, when you step into this shoe you will have a very premium feeling.

This material stretches with your feet providing you with a natural running experience.

Also, it has the 3D Heel Frame. This holds the ankle in place and allows the natural expansion of the heels.

The upper of Asics Gel-Kayano is made from engineered mesh. This is a lightweight mesh that will provide you with a very comfortable fit.

This has good breathability and stretches with your feet providing you with a non-restrictive movement.

Also, it has an external heel clutch. This is an exoskeletal structure that wraps the heels and provides them with a secured fit. Also, it has a ned X-shaped structure that is lined with memory foam. This provides you with a more personalized fit.

It also has the EVA sockliner that provides you with added cushioning.

Weight

In terms of weight, the women’s version of Asics Gel Kayano is lighter than Adidas Ultraboost. However, the weight of the men’s version of these two shoes is of the same weight.

Asics Gel-Kayano weighs around 9.1oz /258g for women and 10.9oz/309g for men.

Adidas Ultraboost weighs around 10.9oz/309g for women and 10.9oz/309g for men.

Price
