Updates to Altra Torin 4 Plush

  • The Torin 4 Plush is an update to one of Altra’s most well-known series of running shoes. This model, though similar in name to the base version of the Torin 4, has been configured to exhibit extra plushness through an increase of 2 millimeters to its midsole height. There is also the addition of a Strobel layer and a cushioned insole.
  • An engineered knit upper serves as the cover system of this product. This material, along with the integrated flex grooves of the midsole and the foot-shaped design of the shoe, enables the inherent capacity of the foot to move through the gait cycle. Targeted traction and extra flexibility are the responsibility of the rubber-and-groove combo of the external pad.


The outsole unit of the Altra Torin 4 Plush is rubber. This material is meant to shield the midsole foam from the abrasive nature of the surfaces. Thus, the integrity and form of the compound are preserved.

The rubber exterior is also responsible for delivering traction over the asphalt. Actions such as brakes. Turns and swerves greatly benefit from such a trait.

FootPod™ is an outsole design that emphasizes the anatomical structure of the foot’s bones and tendons. The rubber elements that cover the midsole look like bones, as well. Moreover, external flex grooves heighten the ability of the muscles and joints to bend as they go through the gait cycle.


Underfoot cushioning is the responsibility of Quantic™, a full-length piece that intends to provide responsive performance via a lightweight package. This technology is also designed to be plush enough to ensure consistent comfort and the feeling of being supported throughout the activity. Quantic™ is an innovation that is used in many of the brand’s updated models, including ones from the trail-optimized Altra Superior line.

InnerFlex™ is a system of flex grooves that have been integrated into the foam of the midsole. The natural bending capacity of the foot is further encouraged by these in-built channels. The toe-off phase is the part that would most likely enjoy such inclusion.

Perf-X is an insole that rests on top of the Strobel lasting board of the Altra Torin 4 Plush. This add-on offers a soft surface on which the underside of the foot can rest. The incognito structure and placement don’t hamper flexibility.


The upper unit of the Altra Torin 4 Plush is made of engineered knit fabric. This material is designed to deliver a lightweight and form-fitting wrap. It has been configured to have tiny breathing holes for airflow and release of warmness from the shoe’s interior.

The Altra logo is printed onto the sides of the silhouette. These synthetic prints are meant to help in the attainment of a secure in-shoe experience. They’re placed relatively close to the lacing system to quickly react to the fit-adjustment.

The heel part features an external counter, but it is not made of hard plastic or a stitched-on fabric. Two printed overlays with reinforced centers serve as the accouterments that hold the heel in place. A fundamental purpose of these counters is to avert any instance of the foot exiting the interior compartment accidentally.

The lightly padded tongue and collar hug the topmost portions of the wearer’s foot. The Achilles tendon, the ankles, and the instep are mainly covered.
