Updates to Asics GT 4000

  • Asics has built an all-new running shoe to join in their GT series—the GT 4000. Loyalists of the Asics brand are at least in-the-know that the GT series is a collection of stability running shoes; in other words, designed for overpronators. The naming convention of the shoes in the GT series correspond with the level of stability and number of features offered. Thus, it is safe to say that the Asics GT 4000 would be their most supportive.
  • The construction of the GT 4000 aims to allow runners to run more distances and improve their performance. This is made possible through the use of Asics shoe technologies that provide energized cushioning, superb ventilation, and, most importantly, stability. All these qualities are materialized in the sole unit, which is equipped with familiar features, such as the Gel® cushioning, Impact Guide System (IGS), and the Asics High Abrasion Rubber (AHAR), to name a few.
  • With the innovation present in the GT 4000, overpronators are assured of a stable ride, no matter their running technique. Those who have already tried the other models in the GT series should expect the same, if not a better, performance in the GT 4000.

Size and fit

The sizing dimensions of the Asics GT 4000 follow a standard running shoe, which means runners should find that it fits true-to-size. Meanwhile, the width options available are Medium and Wide, both for the men’s and women’s versions. This is to ensure that wearers of all foot volumes are accommodated. Runners who prefer plenty of room for toe splay could get a Wide version without having to go a size higher.


The Asics High Abrasion Rubber (AHAR) is linked to a durable outsole structure. Placed in the GT 4000’s high-wear areas, the AHAR material guarantees an outstanding abrasion-resistance and an enhanced grip that keeps up with the pace of the runner. In addition, the AHAR technology is created with a high-quality material that delivers results that are thrice as effective as conventional rubber.


Although visible in the outsole, the Guidance Line is a prominent part of the midsole. This feature is a portion of the GT 4000 that comes in the form of a vertical line and acts similarly to a flex groove. The Guidance Line aims to improve the runner’s gait, as it runs from the forefoot to the heel, by emphasizing a center of pressure so that each stride is consistent and balanced.

The Guidance Line works under the mechanism of the Impact Guidance System (IGS), which allows the shoe to provide a dynamic and adaptive ride. Particularly useful for overpronators, the IGS reduces foot fatigue by absorbing shock; it also prevents foot injuries.

Another supplementary feature of the Guidance Line is the Trusstic System, a shank that aids in maintaining structural integrity without adding bulk to the shoe. With the Trusstic System, the midsole is reinforced, thus promoting stable foot movements. The midsole itself uses the SpEVA material, a proprietary Asics tech that is well-known for its impressive bounce-back quality, as well as its shock absorption capability. The SpEVA midsole is installed with the DuoMax support system, which allows overpronators a sustained ride and a seamless transition. This material could also be found in the other models of the GT series, such as the GT 1000 7.

Lastly, the rearfoot Gel cushioning system in the GT 4000 promises shock absorption and distribution, which contributes to foot protection and enhanced comfort.


The upper of the GT 4000 is built using a sandwich mesh with an open-weave pattern. This material is typically produced from fabric, thus ensuring the foot is well-accommodated and with a comfortable fit. In addition, the lightweight quality of the mesh increases the quality of air circulation received by the foot.

The GT 4000 uses a conventional lacing system to promote an easy method of wearing and taking off the shoe.
