adidas TERREX just gave its most recognizable hiker a full reset. The Freehiker 3 is here, and this generation borrows heavily from the brand’s running lab, pulling the same Hyperboost Pro foam found under adidas road-racing shoes and dropping it into a hiking silhouette built to move just as comfortably through the city as it does on the trail.
If you’ve followed the franchise since the original 2019 Free Hiker, the one that put springy Boost cushioning under a hiking boot and rode the gorpcore wave, this is the third act, and it’s the biggest expansion yet.
A full family, not just one shoe
The headline here isn’t a single release. adidas broke the Freehiker 3 into a complete system so you can pick your level of commitment:
- Freehiker 3 Ultra GTX — the most technical of the bunch, sitting at the top of the range with a speed-lacing system that doesn’t appear anywhere else in the family
- Freehiker 3 Mid GTX — the classic over-the-ankle build for support on longer days
- Freehiker 3 Low GTX — the everyday, sneaker-adjacent option
- Freehiker SL — the all-new, stripped-back addition to the line
Every silhouette runs the same performance foundation, just tuned for different use cases.
What’s underfoot
The cushioning story is where this update earns its keep. adidas paired two midsole technologies new to the TERREX hiking lineup:
- Hyperboost Pro – the responsive, energy-returning foam lifted from adidas’s running innovations, tuned here for long days on rolling terrain
- Dreamstrike+ – a softer, adaptive layer engineered to stay stable across uneven ground
On the Ultra GTX, that translates to a 43mm heel stack, legitimately super-shoe territory, while still coming in at roughly 354 grams per shoe with a 10mm drop. Lighter than before, but adidas says it kept the stability hikers actually rely on.
Rounding out the build:
- GORE-TEX waterproofing across the GTX models to keep feet dry through wet, muddy, unpredictable conditions
- Continental rubber outsole for dependable grip on both technical trail and slick pavement
- A close-fitting sock construction and ripstop upper for durability over multi-day miles
Straight from adidas
adidas Sr. Director of Product Tom Louage framed the goal as doubling down on what made the line iconic, comfort for long days on rolling terrain, while making the shoe meaningfully lighter. The team leaned on its Hyperboost Pro midsole to bring “a new level of cushioning and energy return to the outdoors,” and notably, at a more accessible price point than you might expect from a shoe with this much tech underfoot.
Price and where to buy
The Freehiker 3 family is available now, priced across the range from $150 to $220 depending on the silhouette. On adidas.com, the Low runs $180, the Mid sits at $200, and the Ultra tops out at $220.
