  • The Asics Gel Scram 4 permits the trail runner to accomplish their adventure with speed and ease, as it combines a rugged, outdoor-appropriate design with trail-specific functionalities. The dynamic features of the Gel Scram 4 enable the wearer to trek on uphill and downhill slopes effortlessly.
  • A new unique-combination upper gives the Gel Scram 4 the best of both worlds – breathability and support. The materials work together to deliver a fit that is both comfortable and secure.
  • The Gel® cushioning system in the outsole is coupled by a standard ethylene-vinyl acetate (EVA) foam for a cushioning that is responsive, shock-absorbent, and assistive. The midsole rests on a specially-designed rubber outsole for the ultimate grip.

Size and fit

With a structure that follows the standard running shoe length, the Asics Gel Scram 4 is true-to-size. The shoe has a wide forefoot area to promote a natural toe splay, which is essential for a comfortable trail run, then tapers down to a snug fit at the heel area. The Gel Scram 4 caters to various foot volumes, as it is available in D – Medium and 4E – Extra Wide for men, and B – Medium for women.


The Asics Gel Scram 4 uses a trail-specific outsole. This aggressive rubber material equips the runner with an enhanced footing and encourages a smooth stride, even on the most technical trails.

The outsole pattern of this Asics running shoe is formed by lugs that run in opposite directions. This is to adequately provide traction on any course, and on either upward or downward slope. The lugs’ unique shape also allows the shoe to capably grip dirt or mud without the risk of imbalance.


While it might seem ordinary at first, the EVA foam midsole of the Asics Gel Scram 4 is a successful and efficient component that indicates the shoe performs well on the trails. Its responsive feature gives the runner enough energy in their step to undertake more miles. The midsole foam also offers the essential cushioning that supports the underfoot and protects it from outside elements.

Accompanying the shoe’s main midsole foam is a unit of Gel® cushioning in the rearfoot. This material gives the Gel Scram 4 a shock-absorbent capability in the heel area, a useful quality that helps the shoe, especially during landing. With the Gel® cushioning, the impact of the strike is reduced and dispersed to lessen the pressure felt by the heel, therefore permitting the foot with increased movements. Being one of the most popular shoe technologies from the brand, the Gel cushioning is also present in other Asics running shoes, such as the Gel Cumulus 20.

An EVA sockliner is topped on the sole unit, producing an extra layer of cushioning and shield for the underfoot.


The exceptionally-designed upper of the Gel Scram 4 is composed of a combination of synthetic leather and mesh. The two materials marry together their advantages – breathable, comfortable, lightweight, supportive, and protective.

A reinforced toe cap is placed at the front of the shoe. This unit helps guard the toes against injuries that result from accidental kicking or hitting hard surfaces while running. It also covers the front part of the shoe that has the risk of being torn or damaged by sharp trail elements.
