With sticky 4.8 mm lugs in the Vibram outsole, these shoes provide strong traction on muddy, snowy, or rocky trails, instilling confidence during hikes. However, it is important to note that the Merrell Moab 3 GTX emphasizes ground feel; therefore, individuals seeking maximum impact protection may want to consider more cushioned hiking options.

The La Sportiva Spire GTX is an ideal backpacking shoe for winter hikes, providing warmth, protection, and stability for snowy and unpredictable conditions. Our testing, both in the lab and on the trail, confirmed its effectiveness during various outdoor adventures.

With a heel foam thickness of 39.1 mm, one of the tallest measurements we've encountered, the shoe offers significant isolation from ground impact and debris. The heel features a steep incline of 16.0 mm, which helps reduce stress on the Achilles tendon, allowing for longer treks while carrying heavy loads.

The cushion measures a firm 32.6 HA on our durometer, enhancing overall stability. Additionally, the STB control system includes tall sidewalls that cradle the feet securely, while the Vibram outsole, equipped with 4.3 mm deep lugs, ensures reliable traction on various surfaces.

Designed to withstand cold weather, the upper provides excellent protection against harsh winds, achieving a low score of 1/5 in breathability tests, which is beneficial for winter footwear. However, it’s important to note that the already firm midsole becomes even firmer in colder temperatures, making this shoe less suitable for those who prefer softer cushioning.

The Altra Olympus 6 Hike Low GTX is an excellent choice for winter hikers seeking a comfortable and spacious fit. This shoe prioritizes comfort, providing a plush sensation that has been notably appreciated during snowy mountain excursions. Among the winter hiking shoes we tested, its wide toebox stands out, accommodating even broader feet effectively.

This model features the Original FootShape Fit, which measures 80.5 mm in the toebox, significantly wider than the average of 72.5 mm. This design allows for ample room without sacrificing support. Additionally, the impermeable upper material ensures warmth in sub-zero temperatures, constructed from nubuck leather and the Gore-Tex Invisible Fit membrane.

In our lab tests, the shoe demonstrated excellent impact protection, offering above-average shock absorption rated at 118 SA, which enhances comfort during prolonged trekking sessions. Although the platform height is moderate, it provides sufficient cushioning for demanding hikes.

However, the shoe's stiff construction may be excessive for lighter trails. For casual walks or easy park strolls, a more flexible shoe would be advisable. Overall, the Altra Olympus 6 Hike Low GTX excels in stability and durability for serious winter hikes but may not suit all types of outdoor activities.

The Adidas Terrex AX4 is a stable and affordable hiking shoe, best suited for hikers seeking reliable support on the trail. Priced at just $90, it offers notable value as it is $22 less than the average cost of summer hiking shoes.

This shoe features an ample midsole that effectively prevents ankle rolls, with measurements of 111.5 mm at the forefoot and 87.9 mm at the heel, placing it around the average width for hiking footwear. The stiff heel counter secures the heel during steep climbs and rough terrain, contributing to its overall stability; in lab tests, it received a stiff rating of 5/5.

Despite a slightly lower stack height, the Terrex AX4 enhances midsole performance. Lab testing showed the midsole registering 39 HA, which is 27% firmer than average, providing both firmness and protection while walking on trails.

However, it should be noted that the Adidas Terrex AX4 lacks flexibility for winter hiking.
