Updates to the Altra Duo 1.5

  • The Altra Duo 1.5 is a running shoe that’s designed for those who appreciate maximum underfoot cushioning in a lightweight package.
  • The platform has a zero-drop nature with tall stack heights (33 millimeters for men and 31 millimeters for women). Such a design is meant to deliver consistent and full-bodied support throughout the running session.
  • A foot-shaped last accommodates the natural anatomy of the wearer.
  • Differences between the original Duo model and this iteration are on the upper unit. One particular contrast is the latter’s upgrading the textile to a cloth-like engineered knit material as opposed to the former’s razor-thin mesh.
  • A thin tongue unit and collar enable a freeing in-shoe feel.

Experience confident and safe steps with the Altra Duo 1.5 outsole

Rubber is employed in the outsole unit of the Altra Duo 1.5. This compound is designed to protect the contact points of the midsole’s base from the abrasive nature of the roads. It is also tasked with providing traction for confident and safe steps.

Altra Duo 1.5 rubber

FootPod™ is an outsole design that focuses on the anatomical structure of the human foot. The rubber layers and the tread pattern mimic the mechanical schematic of the bones, heightening flexibility, and surface control in the process.

Deep grooves further encourage the natural bending capacity of the foot as it goes through the gait cycle. A grid-like pattern of these trenches that covers the whole external pad makes sure to give the foot full freedom to move.

Max-LT midsole in the Altra Duo 1.5

The midsole unit of the Duo 1.5 is made of Max_LT™, a technology that is claimed as one of the lightest in the market. This foam piece offers reactive and stealthy cushioning, albeit in a max-stack-height setup. The increased distance between the foot and the ground aims to evoke high-tier support from the impact forces and the elements.

A 5-millimeter footbed is placed right above the primary cushioning unit. This add-on offers a soft surface on which the foot can stand. The incognito profile of this piece doesn’t hamper the flexibility or the lightweight nature of the Altra Duo 1.5.

The profile height of the heel and forefoot are the same. This balanced plane permits the foot to maintain its own sense of equilibrium, thus potentially training the quality of the performance of the wearer. Altra running shoes generally adhere to this zero-drop construction, including well-known series like the Paradigm and the Lone Peak.

Movement without limits with the Altra Duo 1.5 upper

The upper unit is made of an engineered knit fabric. This material is like woven cloth, offering a non-irritating wrap that is also stretchy and breathable. It has the capacity to secure the foot without limiting its movements. The small holes that pockmark its facade permit air to enter the foot-chamber and maintain a cool and dry ride.

Some portions of the silhouette, like the front and the rear, have a close-weave construction with multiple layers of yarn to serve as elements that bolster structural integrity. These layered yarns also help with the attainment of a snug and secure fit by having links to the lacing system.

The left and right sides feature printed overlays that take the form of the Altra logo. These seemingly aesthetic add-ons actually help the rest of the upper unit when it comes to keeping the foot in place.

The tongue and collar of this product do not have padding. This sleek and minimalist design gives more room for the heel, ankles, and instep to move and swell as the running session is taking its course.

A traditional lacing system rests on top of the tongue unit, weaving through discreet eyelets that are reinforced with synthetic prints. This fit-adjustment scheme helps the wearer when it comes to adjusting the tightness or looseness of the wrap.

Altra Duo 1.5 lacececs

A lace-anchor is a loop on the tongue unit that is used to keep it from deviating from the center of the Altra Duo 1.5. The crisscrossing laces snake through this tab, literally locking the instep fabric in place.
