About

The Asics GT-4000 is a pronator road shoe. It offers a high level of correction within the Japanese brand’s range of stability shoes dominated by the Kayano 26 and the GT 2000 8. Like the latter, it relies on an anthology of technologies (Trusstic, IGS) to prevent the foot from deviating outwards. The runners who have tested it find the result satisfactory even if it should be recalled that there is no formal proof that this type of shoe can reduce the risk of injury compared to a classic (ie universal) shoe. In terms of cushioning, we find a sole of moderate thickness with 22 mm thick under the heel and 12 mm at the front. The result is comfortable cushioning, true to Asics’ reputation (including the famous GEL cushioning under the heel). Finally, the upper ensures a pleasant support of the foot while the outsole is solid and offers good traction in the city. However, we regret a high weight with more than 300 grams on the clock (for the men’s model) but this is often unavoidable with shoes for pronators which have an additional upper to wedge the foot. In summary, the Asics GT 4000 is a good pronator shoe for runners looking for push correction.

Technologies

outsole

• First, the outsole of the Asics GT 4000 uses AHAR technology . This consists of a rubber renowned for its resistance to any test for racing on the road. Thus, it improves the durability of the sole. In addition, it is lightly foamed to improve the flexibility of the shoe. The runner can tackle urban surfaces with confidence even in wet weather thanks to the effective grip of the shoe.

Midsole

• The midsole uses spEVA technology . It is a naturally reactive foam. According to the Japanese brand, it provides 20% more rebound than the foams traditionally used in running shoes. Its purpose is to disperse impacts throughout the race for greater comfort.
• On the other hand, there is the Rearfoot GEL technology . It consists of a gel cushioning unit made of silicone found under the heel. This should provide soft impact absorption.
• Finally, there is also Impact Guidance System (IGS) , a system that is supposed to adjust the center of pressure of the platform to help the athlete optimize their stroke and make it smoother. This technology is based on the philosophy of Asics which wants to complement and not change the natural movement of the runner.
• Finally, we find Trusstic System , a thermoplastic element positioned in the midsole under the arch of the foot supposed to guide the runner towards a more fluid stride.

Upper part (upper)

• The upper of the Asics GT 4000 results in a technical open weave mesh . The purpose of this is to wedge the foot effectively during the race for optimal comfort. In addition, it is naturally ventilated to let the foot breathe and thus prevent it from sweating excessively during exercise.
• In addition, the classic lacing system allows the pressure of the laces to be adjusted evenly around the foot to avoid annoying pressure points.

Frequently Asked Questions (FAQ)

How do the Asics GT 4000 fit?

This road shoe uses a regular sizing system. Thus, it must correspond to the advertised size. So you can order your usual size for sports shoes. However, if this is your first pair of Asics, a visit to the store is advised to choose the most suitable size.

Is the GT 4000 suitable for pronator runners?

This model aims to stabilize the stride and thus avoid pronation or supination of the foot during the race. Thus, this shoe is therefore designed especially for pronator and supinator runners who want to correct their stride. Nevertheless, it should be noted that for the moment there are no scientific studies demonstrating the benefits of this type of shoe compared to universal shoes to limit the risk of injury (and this independently of the type of stride of the runner). We therefore recommend opting for comfortable shoes above all.

Is this road model suitable for heavy athletes (85 kg or more)?

To our knowledge, only one study to date has investigated the link between weight, sole thickness and risk of injury. According to its findings, minimalist shoes can increase the risk of injury for runners weighing more than 71 kg. Other than that, there are no recommendations for other types of running shoes. The GT 4000 offers a 22 mm thick sole under the heel which is an intermediate level of padding. Thus, the shoe should therefore be suitable for all runners regardless of their weight.

Is it possible to run a half marathon or a marathon with this model?

This Asics road shoe is suitable for different types of training and distances. So you can put it on during your daily workouts, of any type. In addition, this road shoe offers generous and comfortable cushioning. This makes her an ideal candidate for the marathon!
