Adidas has come on strong in the world of hiking footwear, and its Terrex Swift series is a notable standout among the competition. The R2 GTX is a low-cut waterproof hiking shoe that weighs a reasonable 1 pound 8.6 ounces for the pair but offers surprisingly great protection and stability. After taking it out backpacking in Utah’s Canyon Country, we were impressed with the toughness and hiking boot-like personality of the R2, although it does have a slightly stiffer feel than we’re used to. Below we break down the Terrex Swift R2’s overall performance. To see how it stacks up against the competition, see our article on the best hiking shoes.

We’ll start by noting that the Adidas Terrex Swift R2 feels a bit stiff out of the box and generally stays that way. The design is fairly rigid overall, including a burly sole and tough ripstop mesh upper. This isn’t a huge knock on comfort—the shoe fits snugly around the foot, performed well without a break-in period, and didn’t loosen up or create hot spots. We think the R2 wears like a hiking boot but with a lower ankle and lighter weight. If you’re looking for a flexible, trail runner-like experience where you can really feel the ground beneath you, this is not the hiker for you. But if you want a protective and tough shoe at a low weight, the Terrex Swift is exactly that.

At 1 pound 8.6 ounces for the pair, the Terrex Swift R2 is impressively light, especially for the level of protection you get. For comparison, the popular Salomon X Ultra 3 GTX weighs slightly more at 1 pound 10.8 ounces, while The North Face’s Ultra 111 WP (1 lb. 14.2 oz.) and La Sportiva’s Spire GTX (1 lb. 15 oz.) both come in quite a bit heavier. You can go lighter with a flexible shoe like Salomon X Raise GTX at 1 pound 7.6 ounces, but you do sacrifice some in stability and traction. Pound for pound, the Terrex Swift R2 packs a lot of punch.

Traction on the Adidas Terrex Swift R2 is excellent with deep and durable lugs. Adidas partnered with tire maker Continental for the rubber, and the tread pattern does look surprisingly similar to that of a car tire. It’s hard to tell how much of that is style over substance, but the R2 GTX is grippy on rock, the lugs are substantial and well-spaced (this helps prevent mud from caking), and the rubber is noticeably hard, which should help with longevity. After a backpacking trip in Utah’s Canyonlands, we did notice some slight wear on a few lugs near the toe, meaning the shoes aren’t indestructible and eventually will wear down. But we put them to the test in terms of scrambling on rock with a loaded pack and they performed admirably.

In addition to the low weight, perhaps the single biggest upside of the Terrex Swift R2 is protection. Underfoot, these shoes feel much more like a hiking boot than their design would suggest. Compared to the reasonably burly Salomon X Ultra 3, the Adidas provided even more separation from the trail. We hiked over all kinds of rock in Utah’s Canyon Country but felt none of the sharp corners that you often get with other lightweight shoes. If you like feeling the trail beneath you, we recommend you look elsewhere. The R2 is burly and tough underfoot but certainly not one of the more sensitive shoes we’ve worn.

The protection continues around the toe and sides of the foot. Again, this type of design is rare for a lightweight hiking shoe. The Terrex Swift R2 has almost an approach shoe-like rubber toe with a molded TPU toe cap. In addition, the areas along the balls of the feet protrude with even more rubber, creating zones of extra protection on the inside and outside of the foot. Throw in more hard rubber around the heel above the midsole, and you have one heckuva tough shoe given its weight. It’s worth noting that all of this toughness likely contributes to the overall stiffness of the shoe described above. Protection is great, but it often comes at the sacrifice of flexibility.

Stability and Support

The Swift R2 GTX is a low-cut shoe but is pretty darn impressive in terms of stability. First, the rigid design and stiff structure help keep your foot and ankle in place. Second, the lacing system wasn’t our favorite of its type (more on that below), but it does a nice job in terms of keeping things tight around the foot. When fully laced up, we backpacked in the Swift R2 with an overnight pack and had only a couple of minor ankle turns despite some rocky and challenging terrain. Those who want a step up in support should consider a lightweight boot like the Salomon X Ultra 3 Mid, which goes up higher over the ankle, but it also weighs an extra 7 ounces per pair and costs $25 more. All in all, compared to the low-top hiking shoe competition, the R2 is among the most stable models we’ve worn.

Waterproofing and Breathability

The Adidas Terrex Swift R2 comes with a Gore-Tex liner, making it fully waterproof (unfortunately, it’s no longer offered in a non-GTX version). We did the majority of our testing in Utah and did not give the waterproofing an extended test, but Gore-Tex is known for its quality and almost always has delivered for us in the past. Compared to cheaper types of waterproofing, Gore-Tex creates enough airflow so that your feet can breathe (when paired with a lightweight upper material), which can make a big difference when covering ground in warm climates. It’s worth noting that the Swift R2 GTX does have a low-cut design, meaning that water can enter the shoe when your foot is submerged around ankle level. If you’re hiking in hot, dry places and can easily let your shoes dry when wet, a non-waterproof model likely is a better bet.

Similar to Salomon, Adidas employs a quick-lacing system on its Swift lineup called Lace Bungee. We like the concept, which allows you to lace up and tighten the shoe in one quick motion. But compared to Salomon, Lace Bungee does the job but still falls short in use. We found the lacing action to be a bit clunky and not as smooth, and even the laces themselves feel a little too rigid. However, the lacing system did not come undone or loosen in any way during our hiking, which is the most important thing. But Salomon wins out in overall lacing design, and its Quicklace is tough to beat.

Fit and Sizing

We ordered our usual men’s size 12, and the Adidas Terrex Swift R2 fit true to size. The shoe is slightly wider than comparable Salomon shoes we’ve tested, and if anything, the R2 runs a tad big. If you’re right on the fence between sizes, we recommend going down a half size. But most people with normal to wide feet should be happy with their standard size.

Other Versions of the Adidas Terrex Swift R2

We tested the men’s low-top version of the Terrex Swift R2 GTX, but Adidas also makes a women’s-specific model with a nearly identical design, varying colorways, the same price ($140), and a lower weight at 1 pound 5.8 ounces for the pair. Back to the men’s side, you also can get the Swift R2 in a mid-height waterproof boot ($170 and 1 lb. 13.2 oz.), although there’s no mid-height women’s option. And as mentioned above, Adidas no longer makes the shoe in non-waterproof versions, which is a downside for those who regularly hike in warm climates or plan on encountering frequent water crossings (waterproof shoes take much longer to dry).

What We Like

  • Impressive protection from the trail. The Terrex Swift R2 feels like a hiking boot underfoot but in a more streamlined design.
  • Decently lightweight at 1 pound 8.6 ounces for the pair, especially considering the level of protection you get.
  • Good stability for a low-cut design.

What We Don’t

  • A stiffer and more rigid feel than other lightweight hikers we’ve tested.
  • Adidas’s Lace Bungee works but is less smooth than Salomon’s Quicklace design.
  • If you like feeling the trail beneath you, we suggest looking elsewhere.

The Competition

With its Terrex Swift R2 series, Adidas takes aim at the fast-and-light crowd who want more protection than a trail runner. The elephant in the room is the Salomon X Ultra 3 GTX, which has been one of our favorite lightweight hiking shoe lines for years. The Adidas comes in at about the same weight (a couple ounces lighter), costs $10 less, and offers similar levels of stability and protection (perhaps even a little more of the latter). However, we like the feel and comfort of the Salomon more: it hits that just-right balance of toughness and flexibility, and the lacing system is superior. Unless you favor underfoot protection over everything else, the X Ultra 3 GTX is our favorite hiking shoe on the market.

There aren’t a lot of low-top shoes that can match the Swift’s boot-like feeling of sturdiness, but La Sportiva’s Spire GTX is just that. The Spire is fairly stiff, sturdy, and offers excellent protection and traction across a wide range of terrain. In addition, we think it’s even more comfortable underfoot, although you do pay a premium in both weight (an additional 6.4 oz.) and cost (it’s $50 more). The Spire is arguably the more capable shoe, but it’s hard to justify the big price tag, which is why we prefer the Terrex Swift.Adidas Terrex Swift R2 GTX (Chesler Park)

Another big-time alternative to the Swift is The North Face’s Ultra 111. This shoe is listed as a trail runner, but we consider it one of the tougher and more stable light hikers available. Compared with the Swift, the Ultra 111 has similarly good traction and support, but the Ultra is a little more flexible and has a wider base. The Adidas has the clear advantage in weight, however, at 1 pound 8.6 ounces vs. 1 pound 14.2 ounces for The North Face shoe. In the end, both are quality options, but the Swift’s comparable performance and big weight savings make it worth the added $20 for us.

Another hybrid hiker/trail runner to consider is Arc’teryx’s Aerios FL GTX. Like the Terrex Swift, the Aerios is impressively light at 1 pound 8.4 ounces, uses quality Gore-Tex waterproofing, and is noticeably protective and tough with a robust toe cap and TPU around the bottom section. Similarly, it also had a stiffer and more rigid feel than other lightweight hikers we’ve tested, although it did break in nicely throughout testing and was comfortable over long, high-mileage days with a full pack. Overall, we think the Aerios is the slightly better-built design in this category and many will prefer the traditional lacing design, but the Adidas offers very similar performance for $30 less. Adidas Terrex Swift R2 GTX hiking shoe (Arc'teryx Aerios FL competitor)

Last but not least, La Sportiva’s TX3 technically is an approach shoe but has a number of similarities to the Adidas Terrex Swift R2. Both feel relatively stiff underfoot yet hike extremely well, offer excellent protection around the foot for moving off-trail and over rocky terrain, and cost around the same (the TX3 is $5 cheaper at $135). The La Sportiva comes in a teeny bit heavier than the Adidas at 1 pound 9 ounces, although you give up the Gore-Tex insert for a simple mesh upper that is not waterproof and not a standout in terms of durability (we’ve developed a few tears in ours over time). The La Sportiva TX4 with its leather upper provides a boost in weather resistance and toughness for a mere $5 and 1 ounce more, although at the sacrifice of some breathability in hot weather.
