What Run Oregon is Wearing: UnderArmour Horizon RTT

Run Oregon receives and tests running shoes from time to time. This initial post about the UnderArmour Horizon RTT.

Company: UnderArmour


Specs (from UnderArmour): 

  • Durable PU & textile upper for breathability & reliable protection
  • Reinforced welded synthetic in critical areas for increased durability
  • Mesh heel with dual protective welds
  • Molded collar foam package for added comfort
  • Charged Cushioning® foam puck placed under the heel for responsive comfort
  • Lightweight, full-length EVA midsole for optimal cushioning
  • High traction rubber lug outsole for dependable traction on a variety of conditions

The UnderArmour Horizon RTT‘s were debuted at the Outdoor Retailer in Salt Lake City this past winter. There are a variety of shoes in their Horizon series of shoes, designed to be utilized depending on your trail running styles (from neutral and ultralight pairs to those focused on extreme traction, and all those in between).

Please keep in mind that our shoe reviews don’t get too into the weeds on specs and technology. We pride ourselves on offering helpful information and perspective from a more personal level than many professional shoe reviewers out there. We also acknowledge that there has recently been a lot of discussion surrounding UA as a company. We here at Run Oregon aren’t going to delve into the political realm and will keep things related to running. We  (as always) encourage readers to make their own decisions.

Initial Impressions (Matt):

UA has always been a company that has toed the line of style. I personally like the look of the Horizon RTT, as it’s pretty fashion forward and really doesn’t look all that much like a typical running shoe. It seems that it could be used in a variety of settings (aside from the traction), if you really wanted to. The look may not fly with everyone, but I think it’s pretty unique without being gaudy or “weird”.

I anticipate that these will hold up quite well over time – especially from the top down. The upper covering encompasses the majority of the shoe and looks like it can take a beating. Time will tell if the Horizon RTT is as breathable as the claim.

While there does appear to be a good amount of tread on the bottom, a few walks and short runs around the neighborhood seem to indicate that this would be a solid pavement/earth trail shoe. It feels like it will transition easily between dirt and bark trails and potentially even some small stretches of pavement or other less hardcore surfaces. For someone like myself, who runs in a variety of locations where this is the case, I am happy to see this.


I decided it would be good to test the Horizon RTT out on a walk before attempting a run just to see how they felt on my feet. When I got them on, my first thought was they felt a little snug even though I’d ordered up a half size (I always do this with running shoes to account for swelling and to avoid black toenails.) I also noticed that the tongue of the shoe was different than what I’m used to seeing, as it’s a bit wider and looks a bit like a “mudflap” for lack of a more technical term. My feet are not super wide nor slender, but my guess is that trail shoes should be a little tighter than normal shoes considering the terrain difference. I figure it helps prevent dirt and rocks from getting into the shoes and I also believe that’s the reason for the difference in the tongue as well.

Once the shoes were laced up and I started walking around in them, they didn’t feel constrictive. I also really liked the style and look of the shoe and I received some compliments from friends, so my guess is that others would agree. The shoes were quite comfortable, though I did notice the treads were meant for “grippier” terrain. I think they would do okay on roads, but it’s clear these shoes are more at home on the trails. I’m looking forward to seeing how they do out there in the dirt and mud.
