Shoe Review! Under Armour Horizon RTT

Are they really trail shoes if you don’t get them muddy?

Let’s get this out of the way. I was super excited to be able to test out a pair of the Under Armour Horizon RTT shoes. I’ve always been intrigued by Under Armour’s running shoes (specifically the Gemini), and had heard so many good things about the new Hovr from some of the other BibRave Pros.

Plus, with the Ice Age 50 in May (and the recently passed MCTU) I was stoked to add a pair of trail shoes to my arsenal. Plus, they were blue, my choice of shoe color.


But let’s talk about the actual shoe. I wasn’t sure about UA’s size, but was told they were comparable to Saucony, so I went with a 9.5. The fit is a little snug, and a tad narrow. Now, that’s something that I like in my shoes. But if you want a little more room, you could easily go a half size up, and I don’t think it would be a big difference.

The upper is very sturdy. I know UA bills the Horizon as a neutral shoe, but I think it runs a lot more like a stability shoe. Personally, I think that’s useful to have on a trail shoe, especially if you’re running some gnarly trails.

The sole is fairly aggressive with it’s lugs. I wasn’t quite sure about this. The shoes are billed to be durable, and trails are easier on the sole of shoes, but I was worried the aggressive lugs could wear unevenly. It’s possible that could happen, but so far I’ve got about 50 miles on these and all is well so far.

Let’s talk about running.

I think the shoes run very well. I’ve had no hot spots, and despite the snug fit, no issues on long runs (something which can happen to the best of shoes). Granted, most of my training miles were on fairly tame trails.

Good for dirt and for snow!

However, I got to put these to the ultimate test on and off trail at the MCTU. With mud, steeps climbs, steep descents, and water crossings; I knew I would get a good feel for if these shoes could tackle longer distances.

And boy can they! At no point during the race did I feel like I was sliding up or down the hills, as the lugs did a great job keep traction. The water crossings were a mixed bag. Most importantly, the shoes drained INCREDIBLY well. No water logging even with the multiple crossings, which is key in a long trail race. The downside was that I had literally zero traction in the river. This could have been due to the algae and wet rocks, but I didn’t remember having those issues last year.


But how often will you be crossing rivers consistently?

All in all, these are a light weight and sturdy trail shoe. Even better, these don’t feel clunky on my feet like some trail shoes do. When the time comes that I wear these out and need a new pair of trail shoes, I’ll definitely re-up with another pair of the RTT.

At the least, I’ll be taking these with me to the Ice Age 50, and the Under Armour Copper Mountain 50k as well.
