YMMV Review

Adidas has been an iconic sports brand for many years now both in America and the World. A couple of years ago they decided to branch out into the outdoors here in the US with gear and clothing designed for use on trails and snow in the backcountry.

Adidas has always been known for their footwear so while the first piece I tested from the collection was a jacket. It was only a matter of time before I was able to test a pair of footwear.


I tested the Terrex Fast R Shoes on several different trips. I primarily hiked with them but also wore them around the house and office. On my trips, the weather was dry as these are made for drier weather, and I was not going to risk wet feet. My trips ranged from one to three days. I tested the shoes both with a pack and without for stability purposes.

The Adidas Terrex Fast R Shoes have been built for moving fast in the mountains. While they will work for other activities as well, this is their focus. Starting on the upper, the Fast R has a high-abrasion mesh and synthetic upper to provide breathability and durability. This upper has plenty of synthetic overlays to provide both support and durability. The overlays in the midfoot are connected to the lacing system to secure your foot. There is a toe guard in the front with extra coverage over the toes, focusing on the big toe. In the heel and along the side, there is a tough synthetic heel cup to provide both support as well as durability. The tongue is padded, gusseted and has a foam pre-shaped upper section to allow your ankle to flex and the laces to stay in place. The laces are Adidas’ Speed Laces. These use a tough cord with one hand synching system. There is even a small bungee halfway down the tongue to secure the extra lace. At the back of the foot, there is a loop to make getting the shoes on and off a bit easier.

The interior of the shoe has been finished with a padded mesh in the back half of the foot. In the front half, the inside of the mesh is left untouched. The Fast R has an OrthoLite odor-resistant moisture-wicking sockliner that can be removed if that is your preference. Through the midfoot, there are two different cushioning foams. The forefoot uses ADIPRENE+ to promote forefoot propulsion and efficiency. It protects the forefoot while providing a responsive and dynamic toe-off. The remainder of the midsole uses ADIPRENE to cushion and protect the foot.

Much of the technology in this shoe is located in the outsole. The shoes use the Adidas TRAXION outsole which has been made with Continental Rubber. This rubber is both good for dry or wet conditions with lugs for ample traction. The TRAXION technology provides maximum grip in all directions without excessive pressure points on the foot. In the heel, the Fast R Shoes have FORMOTION Technology. This technology is a heel system that is de-coupled allowing it to adapt to your individual walking style. Your foot experiences a much smoother, balanced, and natural touchdown with FORMOTION beneath your feet.

The actual materials used in the construction of the Fast R Shoes are not easily accessible. I also will note that there is no evidence of sustainable materials being used in the construction of the shoes. There is not a lot of information corporately either. Adidas is large so information is tougher to find. I did stumble across their five-year plan to drive towards sustainability. For this reason, I gave them some credit for their efforts and a 1.5 rating in sustainability.

I had high expectations for my Adidas Terrex Fast R Shoes. Adidas has been making footwear for a long time and should have this down by now you would think. They also we my shoes maker of choice back when I played soccer, so I had a bit of a bias for them from those days. Taking the shoes out of the box and putting my feet in them, I was not disappointed. I am normally a size 9, and that is what I ended up testing in these. Right out of the box the size 9 fit me great. In a pair of hiking shoes, it is important to have a shoe that both are snug enough not to shift around on the foot but also allows for some swelling of the feet over the course of the day. The Fast R can do exactly that. There is a little room beyond the toes, and the toe box is fairly wide. The fit through the midfoot was really good, being both tight but also contoured to the shape of my foot. The heel is a little looser but still felt comfortable. I never had any issues with these shoes giving me blisters or any other problems.

The lacing system does a good job of snugging up the foot and stays in place very well. The laces in all my testing have never loosened up on me on their own. On the other hand, they can get locked in place after a long day on the trail and have been tough to loosen from time to time. At least, there is a rubber piece on the laces to help you pull them loose or tight. Without this, the cord would dig into your fingers quite a lot.

The interior of the shoes is pretty good. They are not the most comfortable again the skin but not much to complain about either. I can from time to time feel both the seams and laces, but his depends on how tight I have the shoes. The synthetic mesh upper is also a little stiffer than some others I have tested so depending on how much they bend when you step you may or may not like the feel. I generally did not have any issues with this other than just being able to feel it slightly. The OrthoLite insole has worked well thus far. Not much to say about it, which means it is doing its job.

I really liked using the Terrex Fast R Shoes on the trail. On all the hikes I did they never let me down. They are a good balance between lightweight and support for long days on the trail. I did several trips in these, and my feet never hurt or were fatigued at the end of the day. I was also not dying to get them off which is a good testament to any hiking footwear. There is ample protection from rocks and debris even without a rock plate. Even with a pack on in rocky terrain I did not have any instances of rocks poking the bottom of my feet. The shoes use two different midsole foams and the FORMOTION technology in the heel to provide a smoother and more stable experience. I personally could not tell if there was any great difference. The shoes felt stable and comfortable walking along, but I do not know if the difference was easy to quantify compared to any of my other hiking shoes. These features did not hurt anything, that is for sure; they just were not easily noticeable either.

I did like the upper mesh material used as it breathed well but also kept dirt and debris out. Some mesh uppers will let lots of dust through, and this can eventually cause comfort problems if you are not careful. This was not the case with these. I felt like they breathed well enough, but a truly open mesh will breath slightly better but will have the dust problem so this is a great compromise. There is a bit of water resistance with this type of mesh as well but only a little. Any substantial amount of water will get your feet wet.

Thus far the shoes have held up well with no durability issues. The only part that worries me is the laces, but I have not seen any reason to be concerned yet. I have had to yank on them pretty hard to get them loose when they have gotten stuck, and they have held up to that so far. The outsole still looks brand new. It is made of Continental rubber who also makes car and bike tires, so I am sure it will handle hiking with relative ease. Not only is the rubber very grippy but the large lugs give plenty of traction across all surfaces. I have not had any issues with traction thus far. Even in the little snow I have had them in this winter they have gripped well.

Overall ★★★½☆

Overall, the Adidas Terrex Fast R Shoes are a very comfortable fast hiking shoe. They are a good balance between light weight and having all the features you look for in a hiking shoe. I have been very happy with the sizing as I felt like it was very true to size. The other standout is the continental outsole that both are very grippy and has shown good durability thus far. The speed laces a very good at securing your foot, but have been too good at times as they do not loosen as easily. Some of the other features on the shoes are a bit more difficult for me to distinguish but the shoes feel great, so I assume that they are working. I would definitely recommend these a fast hiking shoe. They are comfortable and a good balance of features and weight. The Adidas Terrex Fast R Shoes retail for $160, which is on the higher side for a dedicated hiking shoe. It is also available in women’s, Gore-Tex, and Mid options if you need it. As always, your mileage may vary.

  1. Hi,

    I have a pair of these and the speed laces are wearing though only after a couple moths of having the shoe. There is no way to replace them so an otherwise great shoe is about to be worn out.
