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.



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.


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.


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!

  1. I absolutely love these shoes too, but have had the exact same split in the sole – seemingly where the two foams and the ‘torsion system’ meet – at only 150 miles… I initially wrote it off too because I loved the feel of them so much, but in truth, that seems like a design and durability problem to me.
