adidas Terrex Free Hiker 2 Review & Sizing Guide

Published Updated

Buy Terrex Free Hiker 2 for supported, cushioned multi-day hiking with Continental grip and Boost ride that feels good through long days; skip it if you want lighter weight, a more breathable upper for hot summer, or a more traditional stiff hiker with full ankle support for heavy loads I liked the density of the Adidas model... I weigh 145kg (320lbs) and therefore I need some extra support.

FAQ

Is the Terrex Free Hiker 2 a good Tour du Mont Blanc shoe?

Yes, it is the explicit upgrade many TMB hikers reach for after wearing through older Terrex pairs. A buyer with a worn-through pair of Terrex prepping for TMB updates their post specifically to confirm they ordered the Free Hiker 2.0 GTX Had these Adidas Terrex for a few years. Very comfortable and I was planning to wear them for the Tour Du Mont Blanc... UPDATE: Just ordered some Terrex Free Hiker 2.0 GTX. For 110-mile multi-day hut traverses with moderate packs, the Free Hiker 2's Boost cushion is well-suited. For heavier-load backpacking, choose Salomon Quest 4 GTX or Hoka Kaha 2.

Will Terrex Free Hiker 2 work for heavier hikers?

Yes, and heavier owners specifically call out the support density as a plus. A 145kg (320lbs) hiker shopping for replacement trainers with daily wear and hiking use mentions liking the density of the Free Hiker 2.0 Low GTX and finding it supportive without being overly soft I weigh 145kg (320lbs) and therefore I need some extra support. I don't want a shoe that's too soft and 'feel like you're walking on dreamy pillows'. I liked the density of the Adidas model. The trade is breathability: heavier hikers also tend to run hot, and the GTX version traps warmth. For hot-region heavy hikers, the non-GTX version is a better buy.

How does Terrex Free Hiker 2 compare to a traditional hiking boot?

It splits the difference between a sneaker and a boot, which is exactly what some hikers want. A Switzerland-first-time hiker who tried multiple brands and chose Hoka Kaha 2 GTX afterward considers Adidas Terrex specifically as the lighter, more breathable, more flexible direction for next time might have been more utilitarian for me, as I am only going long hikes on vacation once or twice a year. If you want a one-shoe-quiver that walks like a sneaker and grips like a hiker, Terrex Free Hiker 2 wins. If you carry heavy loads in technical terrain, a real stiff boot is still the better buy.

Should I size up in Terrex Free Hiker 2?

Most owners stay true to size, and the sock upper accommodates a wider range of foot shapes than a traditional hiker last. The size-availability problem matters more than the size-up question for many buyers: a Sweden-based buyer specifically reports their size has been out of stock for months unfortunately, my size has been out of stock in Sweden for a few months now, so buy your in-stock size and lace down rather than wait for a half-size-up colorway. For multi-day hiking, plan for foot swelling, pack thicker socks, and choose a half size up if your Adidas usually runs snug; the Boost midsole compresses slightly under sustained load.

How long should Terrex Free Hiker 2 last?

Several years of regular hiking is realistic, with sole wear being the most common end-of-life signal. The TMB-prep post is itself from a hiker who got several years out of their previous Terrex before the soles wore away enough to matter for a 110-mile commit Had these Adidas Terrex for a few years. Very comfortable... the soles have worn away quite a lot. Boost foam holds shape better than EVA; the Continental rubber outsole wears predictably. Plan to replace at 400-500 miles or when you can see lug edges rounded smooth.
