ALTRA LONE PEAK 4.5 – SHOE REVIEW

by BRIAN METZLER | APRIL 2020

THE BUZZ

The Lone Peak 4.5 represents the evolution of the original trail shoe that helped Altra launch a new paradigm in shoe design a decade ago. The brand was founded on
the idea that runners are best served by running in shoes with a level platform with a wider toe box to allow their feet to move and flex naturally, as they do when they’re barefoot.

The Lone Peak is a versatile, amply
cushioned shoe with a moderately aggressive outsole and conducive to running on a wide range of trail surfaces.

Altra Lone Peak 4.5 - What's New

WHAT'S NEW: ALTRA LONE PEAK 4.5

The latest edition of the Altra Lone Peak has been overhauled with a new midsole foam formula, a slimmed-down upper and an updated lacing system. Those changes have
resulted in an easier-flexing demeanor, a more secure, locked-down fit and more resilient and more long-haul cushioning and comfort. The bottom line is that Altra made a very good shoe much better.  

Other key features
include a quick-drying mesh upper that provides breathability, protection and a more structured fit, a gaiter attachment to secure Altra’s Trail Gaiters (sold separately) for over-the-ankle protection against debris and a MaxTrac
Outsole that has anatomically-oriented features that align with the positioning and movement of the metatarsal bones and toes.

Altra Lone Peak 4.5 - Fit and Feel

FIT-FEEL-RIDE

The Altra Lone Peak 4.5 has a comfy, cushy step-in feel that is accentuated by the updated lacing system and new upper that allow for micro-adjustments and a more
secure fit. Combined with the easy-flexing behavior, the shoe feels pretty much like it’s an extension of your foot. With 25mm of stack height under your feet, this shoe won’t feel like it has too much cushioning or too little
for most conditions, but just the perfect amount.

The Altra Lone Peak 4.5 is able to tackle a wide variety of terrain with aplomb because it has a rock guard embedded in the midsole and the outsole offers a combination
of grip, traction and durability with low-profile lugs.

More than ever, the Lone Peak can smoothly adapt to mild, moderate and technical terrain. The increased flex makes it feel better on smooth, dirt trails, while
the subtle but significant rock guard keeps sharp rocks from creating a stinging sensation under your feet.

WHO'S IT BEST FOR?

While all levels of trail runners will appreciate the Lone Peak 4.5, experienced trail runners who typically run on moderately technical and more challenging terrain will love this shoe the most.

While it runs well over
smooth dirt, the biggest selling point of the Lone Peak 4.5 is its versatility and its ability to conquer rugged terrain, too. 

Also of note, Altra’s women’s models are built with Fit4Her Technology, a design system
that caters to the specific anatomical differences of female feet — specifically a narrower heel and midfoot, a higher instep, a longer arch and unique metatarsal spacing.

PROS AND CONS: ALTRA PROVISION 4

Altra Lone Peak 4.5 - Pros

Pros: Altra LonePeak 4.5

All Altra shoes are built with a “Footshape” toe box that is wider and more rounded than most other shoes, thus allowing a runner’s toes and the tranverse arch to
splay and flatten to allow for more effective muscular output when a foot lifts off the ground at the toe-off phase of a new stride.

The midsole is primarily comprised of a resilient material called
A-Bound, a recycled, eco-friendly compound that provides exceptional impact cushioning and energy return. The cushioning and the flexible StoneGuard offer protection from roots, rocks and other trail debris without inhibiting the
natural flex of the shoe and foot.

The reason Altra builds its shoes on a level platform is to allow the heels and forefoot of a runner’s foot to always be an equal distance from the ground. Unlike shoes with lifted
heels and sloping profiles, Altra’s shoes creates what the brand calls an optimal alignment and that cultivates better running form and encourages a low-impact foot strikes.

Altra Lone Peak 4.5 - Cons

Cons: Altra LonePeak 4.5

The Lone Peak 4.5 isn’t heavy but it isn’t the lightest trail shoe in its category, either.

If lightweight shoes are more of your jam, you might find
this slightly heavier on smoother trails. But what you give up weight, you tend to sacrifice in protection, durability and comfort.
