Updates to Asics Gel Flux 2

  • The Asics Gel Flux 2 is a running shoe that’s great for daily running sessions and exercise times. It has high quality components and features that work in tandem in order to provide a smooth performance. It’s most efficient when used on flat surfaces, such as roads and interior areas. An appealing look makes this shoe visually endearing to modern runners.
  • The upper unit of this shoe makes use of a fabric that’s breathable and durable. It is able to effortlessly let air into the foot-chamber to provide a well-ventilated environment for the foot. It doesn’t tear apart easily, and it doesn’t feel firm. The runner can rely on this shoe’s upper unit to provide a secure coverage that’s long lasting.
  • A full-length foam unit keeps the foot cushioned at all times. It doesn’t break down easily, but it’s certainly lightweight and flexible. It is able to make each step more energized because it returns energy to the runner. Its springy nature allows the foot to bounce back up to a more efficient toe-off. Shock is absorbed by gel-like units in the forefoot and heel sections.
  • Two rubber units are used for the outsole unit of the Asics Gel Flux 2. While both of them are able to protect the rest of the sole unit from abrasion and wear, the forefoot section’s rubber compound is able to add more cushioning and flexibility because of its mildly responsive nature.

Asics Gel Flux 2 size and fit

Regular sizing schemes are used for the Asics Gel Flux 2. The men and women’s sizes follow the standard measurements for length. The semi-curved shape of this shoe adheres to the natural curvature of the human foot, enabling runners to fit well into it when wearing it. It has a medium width.


Outsole

The AHAR® or Asics High Abrasion Resistant Rubber is a high quality unit that’s used in the Asics Gel Flux 2. Placed in the rear of the platform, it shields the rest of the sole unit from wear and tear. It also gives reliable traction on the roads.

The DuraSponge® is blown rubber placed in the forefoot section. Aside from being able to resist abrasion, it also adds a bit of cushioning because of its mildly spongy nature.


Midsole

The SpEVA® is a full-length foam unit that has bounce-back mechanics, which means that it is able to spring the foot back up with energy. It is durable, so it won’t break down easily, even after many uses.

The Gel® Cushioning System is a silicon-based gel unit that’s placed in both the rear and front sections of the mid-sole. They are able to absorb shock during the landing and toe-off phase of the gait cycle, keeping the runner comfortable at all times.

The Guidance Trusstic System® and the Guidance Line® provide some support to the mid-foot and keep the gait as efficient as possible. They’re assistive add-ons, and they’re helpful.


Upper

Breathable mesh is what makes up the main cover system of the Asics Gel Flux 2. It enables air to easily invade the interior of the shoe in order to provide a well-ventilated wearing experience for the runner.

Synthetic overlays connect to the lacing system and hug the foot snugly. When the shoelaces are adjusted, the upper follows suit because of these overlays.

Reflective coating allows the shoe to be more visible during nighttime runs. It’s a helpful way to add safety to the running experience.
