I have used adidas shoes for many years both in road and trail versions, Adizero Adios were a personal favourite and recently I enjoyed using the Skychaser based on the laces and the excellent Continental outsole.
The Terrex range which is basically the outdoor/ trail running line of adidas really has some excellent products, so, when I was sent a pair of TERREX TWO BOA to test I was intrigued and interested.
The BOA® system (more info HERE) has been around many years. I actually first used the Boa fastening system on cycling shoes and to this day, I still do; it is my preferred method for fastening. Trail running, I used a pair of The North Face shoes way back in 2008 and recent years I have seen the system used in running packs, inov8-8 and Raidlight have used the fastening system in many products.
So, the BOA system for the new adidas really had me interested.
First off, the Terrex Two Boa is a great looking shoe, it comes in several colour options, but the black/white version I have on test is my favorite. The BOA system sticks out on the side of the shoe with the very obvious fastening dial, it is the USP of the shoe. If you are new to BOA, the system works by one lace threaded through the shoe. Press the BOA button and you engage the ‘lock’ system, turn the dial and the lace pulls tight. The more you turn, the tighter the laces become. To release, you pull the BOA button, and this works like a quick-release and the lace immediately becomes lose.
The shoe is 5mm drop and cushioned with 19.5mm at the front and 24.5mm at the rear of EVA. The drop is a great compromise and sits in a nice middle ground, however, I wonder why adidas chose 5mm instead of the more obvious 4mm?
The upper is seamless mesh with TPU overlays and is extremely comfortable. The heel box is plush, comfortable and holds securely. The toe box is very wide – very wide! So, if you need wide shoes, the Terrex Two Boa should be on your list to check out, it is one of the widest shoes I have used.
The outsole is by the German company Continental™(more info HERE) who are famous for making car and cycling tires. The outsole is one of the stars of the adidas Terrex range – it has incredible grip in the dry and wet. In my opinion, it is one of the best outsoles. The Terrex Two Boa has a classic ‘trail’ outsole that is designed for trails without too much mud.
As I said, the Terrex Two Boa is a great looking shoe. Slipping the shoe on you immediately feel how comfortable the upper is and how cushioned the shoe is. They feel like slippers. You also notice how wide the toe box is. Engaging the BOA system, I tightened the lace by turning the dial and when I felt I had the appropriate tension on my instep I stopped.
I always use any run shoe in my apartment for one day to get a feel of the shoe. My immediate thoughts on the Terrex Two Boa was comfy, cushioned and excellent grip. However, with the wide toe box, I found that I wanted to add more and more tension to the lace to hold my foot secure. But once tightened, the BOA system never comes lose. A great plus.
On my first run which is on a classic 8-mile loop that includes a little of everything – mud, trail, dry single-track, stones, rocks, climbs, descents and also 2-miles of road, I was impressed with the shoe. They are really comfortable. The cushioning provides a nice bounce without losing a feel for the ground below. The Continental™ grip is really great – it grips everything and on rocks it is superb, be they wet or dry. It is a reassuring outsole.
Midway through the run I decided that I didn’t have my laces tight enough. There were two reasons for this:
- When the trail was technical, and I was changing direction, my foot was moving inside the shoe. This is not good!
- The toe box is wide, and I think maybe a little too wide for me. But to compensate for such a wide toe box, I needed to make the laces tighter. To hold my foot secure.
So, I turned the dial, the laces tightened, and they immediately felt better. On all runs that followed, I made sure I really tightened my laces to the maximum. It made my runs so much more pleasurable.
As a trail shoe, the Terrex Two Boa worked exceptionally well. It handled everything on my normal trail/ test loop and the mile of road at the beginning and the end was extremely comfortable. It would be a great ‘jack of all trades’ shoe.
PROS and CONS
The USP of the shoe is the BOA system and this may well put some people off immediately – does it over complicate something that doesn’t need to be complicated? One thing is for sure, break a lace when out running or racing and you are screwed… But the laces rarely break, however, the chance it can happen may be enough for some.
I often like to adjust my laces (I have a high instep) so that I can have good tension at the bottom and the top of the lacing section, but a little lose towards the top. With BOA there is no option for this. Turn the dial and it tightens as one.
I personally found the toe box so wide I wanted to really have the laces tight. However, once really tight I enjoyed the shoes. If trails were rocky and technical, I would prefer to use a shoe that had a precision fit. The Terrex Two Boa just had too much room for me. BUT for long-distance trail runs, the shoe is really comfortable. The toe box allows their toes to splay and the cushioning provides great comfort.
The Continental™ grip is a winner but if you are going in mud, you need a more aggressive outsole.
There is a great deal to like in the Terrex Two Boa. It is a great ‘all-rounder’ and as such I can see this really appealing to runners who are transitions from road to trail and need something that can handle a little of everything. If you have wide feet, check these out, they may well be the shoe you have been looking for. The looks of the shoe are great, and the outsole is excellent, the upper comfortable and has no hot spots. The BOA system works really well and only you can decide if the system is something that you can use and be happy with. I personally love the system, it works really well, once tightened it doesn’t come loose and when you have finished a run, you just pull the dial and you can slip the shoes off. The downsides are the lack of ability to adjust tension at different points – they are either tight or loose. The other aspect, although I had no issues or worries, if the lace breaks, you need to send the shoes away to be fixed.
The Terrex Two Boa for me is a great shoe that I can use for pretty much any run, be that road or trail. It’s a perfect travel shoe when you may be compromised on space and just need a shoe that can handle a little of everything. For those runners who don’t want to spend a great deal of money on shoes and have a specific shoe for trail, road, mountain and say sand for example, then the Terrex Two Boa would be a great option as a one shoe does all. The price is good too at £109 rrp – BUT, they are wide and for many runners, they may well be too wide?
