Adidas TERREX FREEHIKER 3 Ultra GORE-TEX Hiking Shoes
The original Freehiker put Boost foam from running shoes into a hiking boot and helped launch the gorpcore wave in 2019. Six years and two generations later, Adidas is raiding its running lab again, but this time the technology it borrowed is more ambitious.
The Freehiker 3 Ultra GTX replaces Boost with a dual midsole combining Hyperboost Pro and Dreamstrike+ cushioning, the same foam stack found in Adidas road racing shoes. The result is a 43mm heel stack that sits squarely in marathon super shoe territory, yet each shoe weighs just 354 grams. For a GORE-TEX mid with this much cushion underfoot, that weight is genuinely impressive. The ride is designed to feel soft without collapsing laterally, giving you energy return on flat approaches and stability when the terrain breaks up.
Waterproofing comes from a full GORE-TEX membrane across the entire range. Adidas has streamlined the lineup by dropping the non-GTX option entirely, which simplifies the choice without removing the feature most hikers actually want. The sock fit collar wraps the ankle and seals out dust and grit, a detail that matters more on multi day hikes than it does on a morning walk. Speed lacing cinches everything down in one pull and is exclusive to the Ultra, the top tier model in the new three shoe Freehiker 3 family.
The Continental rubber outsole returns for grip across wet and dry surfaces. The upper has been reworked to be more flexible than the Freehiker 2 while maintaining the same level of structure and protection. The overall build is lighter and more nimble than its predecessor without sacrificing anything that made the franchise work in the first place.
The Freehiker 3 comes in three versions. The Low at $180 for day hikes and travel. The Mid for ankle support and general trail use. And the Ultra at $220 for backpacking and more demanding terrain, with the higher collar, speed lacing, and the most complete feature set in the range. All three share the same Continental outsole and GORE-TEX construction.
