adidas Terrex Speed Ultra Long Term Review

I have just retired my adidas Terrex Speed Ultra shoes…. Looking at the photo above, you may well be thinking that this is going to be a harsh look at how the shoe has lasted long term! For perspective, please read my adidas Terrex Speed Ultra shoe review first.

Look different when new – adidas Terrex Speed Ultra

I received my Terrex Speed Ultra in February and now 4-months on and 834km later they have given up! A recent 5-day trip to the mountains of Jotunheimen in Norway and 168km of rocks, snow, ice, mud and harsh terrain pushed them to the limit and over. Even on the final day of 33km with the right upper torn, the shoes performed perfectly.

I am reluctant to retire them!

Without doubt, the Speed Ultra have not only been a highlight shoe of 2021, but they are a highlight shoe in my collection of run shoes, and trust me, I have many, many pairs.

Until the recent run trip, the Speed Ultra was holding up really well, the upper showed little deterioration and the Continental outsole, while showing wear on key strike points, was still good.

Some may say that they want more life out of shoes than 800km. Not me, I am super happy with 800km and especially when the ride and feel is as good as it is in the Terrex Speed Ultra.

Terrex Speed Ultra in action

I have not found a shoe yet that comes close to the Terrex Speed Ultra that manages to combine grip, comfort, flexibility and pure enjoyment. No matter what terrain, this shoe has been awesome.

On road, they have excelled. Modelled on the Boston 9 road shoe, you can feel the adidas road shoe experience here, but, I would go as far to say that on road, I have preferred the Speed Ultra over the Boston. Alternating them, the Speed Ultra gave me more fun and more bounce – a real winner.

On trails, the Continental grip has been superb offering secure confidence on rocks, roots, and hard trail in the wet or dry. It’s not an aggressive outsole, so if you encounter lots of mud, there is a compromise to be made.

The toe box was wide allowing for toe splay but it did not compromise precision and this is no doubt due to how well the Speed Ultra holds the foot via the lacing and excellent fit. The 8mm drop is just superb for comfort, and the cushioning of 18/26 was perfect in managing long-term comfort with no loss for a feel for the ground.

The upper was extremely breathable and as such allowed feet to remain cool, allows water to disappear quickly, however, running through snow and water, I certainly had less insulation.

GOOD and BAD

GOOD

The Terrex Speed Ultra been a joy to use and without doubt are my favourite shoe. So much so that I have now ordered two pairs to replace the sadly retired test pair. Comfort, grip, great design and a shoe that makes you want to run longer, farther and faster.

BAD

After a complete smashing up, the upper has torn and the outsole has split. However, both these failures came at the shoes life expectancy end and on some of the most harsh terrain and conditions you can put a shoe through. I really have thrown everything at this shoe, plenty of road miles to wear down the Continental grip and then mud, snow, ice and rocks. In all honesty, I used the Speed Ultra for the last fastpack as I knew at the end of it I would be saying goodbye. While the upper and outsole tearing could be seen as bad, I see it as just the end of the shoes. However, had this come early, then without doubt I would be asking questions about life/ durability.

Conclusion

The adidas Terrex Speed Ultra is my shoe of 2021 so far and the shoe I want to use on a daily basis, irrespective of the conditions. Light, responsive, fun, fast and great grip. I want nothing more from a shoe and yes, they look pretty darn good too!

adidas Terrex Speed Ultra Shoe Review

I review a great deal of shoes. In the last 12-months alone, I have worked my way through over 20 different pairs and models. In all honesty, running shoes these days are generally all good. Yes, some are better than others but it’s all personal, what works for one, may not work for another. There are so many variables; drop, cushioning, support or the lack of it, toe box width, lacing, upper and I could go on.

So, if the shoes are neutral, I am pretty much always able to run in the shoe irrespective of the toe box width and drop. Actually, I like switching drops and currently, I use 0 drop through to a very rare 12mm (which is. Winter stud) drop. In regard to toe box, if I am running on technical terrain, I much prefer a narrow/ precision fit which gives me an assured control, by contrast, when running longer and on less technical terrain, a wider toe box provides more toe splay and comfort.

I guess what I am saying, no one shoe does all things!

Recently, a couple of shoes have excited and the latest is the adidas Terrex Speed Ultra.

I first heard rumblings of this new shoe well over a year ago, good friend, Tom Evans and adidas Terrex athlete was involved in the design process and it was clear, via his results, that a fast, light and responsive trail running shoe was coming. A win at Tarawera in New Zealand and 3rd place at the iconic Western States set the stage. 

I have to say, I always love getting new shoes. Opening the box of the Terrex Speed Ultra was a real surprise, the colour way and look was really impressive.

Tom Evans

I messaged Tom, “I have got the Speed Ultra!”

“…they are 2 years in the making!! And one of the main reasons I joined Terrex! Hope you like them, I’m SO happy with how they turned out!” was the reply.

FIRST IMPRESSIONS

The colour way was an instant eye catcher (a black and white version is also available) with a mix yellow, greens, grey, black, white and a flash of pink. adidas list the colour as, Cloud White / Solar Yellow / Matte Silver.

Cloud White / Crystal White / Core Black

On the side is a ‘240’ which signifies the weight (typically for a UK8.5) and trust me, these are the lightest most ‘floaty’ trail running shoes I have had the pleasure to hold. Incredible!

The upper is seamless and like a fine sieve used in a Michelin star restaurant with minimalist overlay at the toe, the side and the heel. The drop is stated in the side, 8mm.

Inside the shoe, there is another layer which adds more structure, it’s super thin and its pattern can be seen from the outside of the shoe, particularly at the front where you see lines that move around to the side of the shoe.

The cushioning is solid at the front and as you move to the rear of the shoe, you get to see the ‘bubble’ like boost. ‘Lightstrike’ is written in the cushioning. Lightsrike provides energy return, cushions every stride and provides comfort over the long-haul of an ultra. Cushioning is 18mm at the front and 26mm rear – this is confirmed on the outsole along with the 2.5mm lugs.

The heel area is well cushioned, and the tongue is minimalist with holes all over to reduce weight and add breathability. It’s not a sock liner fit but it is attached at the sides which provides a more secure hold of the foot and instep.

Turning the shoe over, the outsole confirms the shoes intended use – hard, dry and fast trails. The Continental rubber has multi-directional 2.5mm lugs and in the middle, there is a cutaway for the ‘Torsion System’ which provides a thermoplastic arch bridging the heel and the forefoot assisting them to move independently and adapt to various surfaces.

IN USE

It’s just a wow! It’s been a long time that I have pulled on a shoe, run 12-miles off the bat and not taken the smile off my face because the footwear is just bouncing me and pulling me along and tempting me to run at a pace that I can’t maintain.

The Terrex Speed Ultra is quite simply stunning!

Fitting true to size, (I use EU44 272g) slipping the shoe on the toe box is that wonderful middle ground of having enough width to allow toe splay, but not so wide that you don’t have precision or control. Now of course, how the shoe fits does depend on the individual, but based on all my shoe reviews, the Speed Ultra is a wonderful middle ground.

Foot hold is superb, the thin tongue is padded enough for comfort but still allows for a great tight fit. The 6 eyelets allow for great lacing and hold particularly on the navicular bone. There are two ‘additional’ eyelets at the front to adjust lacing and at the top, there are the two additional eyelets that would allow lock-lacing or similar. The upper is extremely breathable.

The cushioning is immediately noticeable and although neutral, there does feel just a hint of support under the arch. It’s minimal! The Speed Ultra is not soft and squidgy, they somehow manage to balance soft and firm. Maybe this is the mix of boost and Lightstrike? The 18/26 cushioning is superb and still gives feel for the ground.

The shoe needed no bedding in, from the off they were comfortable and just felt superb. They forced me or influenced me to run with good technique and constantly they enticed me to go faster. It has been a long, long time that I have had a shoe that made me want to open up the throttle. Hitting the ground, the cushioning was firm but equally soft enough to propel me forward… Had I been told that this shoe had a super thin carbon plate inside, I would not have been surprised. The heritage of adidas making road shoes can be felt here in the Speed Ultra. After all, hard trail and single-track is very similar to road. The difference primarily comes with the outsole.

The outsole is by Continental and they make great rubber which really provides a secure grip in wet or dry. The 2.5mm lugs quite simply are for hard and dry trail, this is NOT a muddy trail shoe. As Tom Evans has shown, hard, fast and long ultras such as Western States are the terrain for the Speed Ultra. This shoe would be amazing for many US trails.

Road or hard trail, the Speed Ultra switches between the two seamlessly and in all honesty, if I was running a road race, the Speed Ultra would be my shoe. It’s that good! The Continental outsole also provides a little more security and grip. Now of course, I am not ‘competing’ for a win in a road race, so, the marginal gains from a specific road shoe may well prove a better choice. Tom Evans for example, after all he did run 63:14 for a half-marathon and I am sure he used a specific road shoe.

On trail, if it’s hard, rocky, tree routes or single-track, the Speed Ultra performs. The shoes fly along managing to provide precision and comfort all in a great package. The 8mm drop and cushioning provide all the comfort needed for a long day, hence the ‘ultra’ in the shoe title.

Ultimately, the Speed Ultra is one of the best shoes I have used in a long time.

SUMMARY

This is a glowing review. To clarify, the shoes were provided to test, as are all the shoes that I review. But this is not a paid review.

The Speed Ultra is one of the most exciting shoes I have used for some time. They put a smile on my face, and they tempted me to run longer.

Comfortable, secure and pleasure to wear. The Speed Ultra is going to be on my feet for any dry trail or road run for some time. On trail, the drop and comfort are perfect be that on gravel, path, hard pack single-track, rock or tree roots; wet or dry. However, this is not a shoe for mud or sloppy terrain… The outsole is not up to the job of gripping in soft stuff and for me, the cushioning would have me to high off the ground, I prefer to be lower and feeling the terrain when it is more challenging. Not a criticism of the shoe, just a clarification of how the Speed Ultra should be used.
