Delivers on durability

The outsole unit of the Altra Lone Peak 4.0 is made up of the MaxTrac technology, a compound that is durable and able to withstand the damaging nature of the surfaces.

This layer is also constructed to provide surface adherence, a property that is highly essential when traversing uneven topography.

Lone Peak 4.0 comes with grippy curved lugs

Curved gripping lugs form the TrailClaw configuration. These prominent nodes act like hooks that clamp onto the ground, thus delivering heightened grip. The opposite-facing layout enables foot-to-ground control during upward and downward traversals.

The trail rudder is fundamentally an extended outsole structure. The extra length permits additional surface control, especially when handling descents.

Provides robust cushioning 

The A-Bound technology is a full-length topsole that’s designed to provide robust cushioning to the underfoot of the wearer. The material itself is made using environmentally friendly materials to reduce material wastage and buildup of plastics.

Ethylene vinyl acetate (EVA) is an industry-standard compound that’s used for many running shoes. This piece acts as the midsole foundation, supporting the top layer and the foot at the same time. It doesn’t sag quickly or lose structure after each run.

Protects the foot from the abrasive elements

The StoneGuard technology is a sheet of thermoplastic polyurethane (TPU) that is sandwiched between the midsole and outsole. The job of this layer is to protect the foot from the abrasive elements on the trails.

It’s robust but flexible enough to follow the natural movement capacity of the foot as it bends and gears itself for each step.

Additional cushioning is provided by the 5-mm contour footbed. This extra piece can be removed or replaced with a custom orthotic insert if the wearer chooses it.

Altra Lone Peak 4.0 is a breathable trail shoe

The upper unit of the Altra Lone Peak 4.0 is made up of the Quick-Dry Air Mesh. This fabric offers breathability and security without luring in trail debris. Ventilation holes are present in this material, but they’re not prominent.

The Quick-Dry distinction means that it’s made to stave off water absorption and retention. The Heel Claw construction involves the curved collar design that’s supposed to clamp the back of the foot and keep it in place.

The padding that graces the shoe’s rear also helps when it comes to preventing accidental shoe removals and in-shoe wobbling.

Ensures optimal coverage and protection

The stitched-on overlays of the Lone Peak 4.0 are meant to shield the mesh from scratches and potential cuts. They’re also intended to help the traditional lacing system when it comes to adjusting the tightness or looseness of the fit.

The 4-Point Gaiter Trap is comprised of several overlays on the upper unit that are made to be anchors for separately-purchased gaiter attachments. The four spots that welcome the hooks of the gaiters ensure optimal coverage, thereby protecting the foot from the elements.
