    Overall, the construction is excellent. Super comfortable. Super durable.

  • 80 / 100 | Runner's World | Level 5 expert

    After three miles I noticed that I had been gripping with my toes, as if holding on to the tire beneath my feet. Relaxing, I found the stretch upper held me in place just fine. The shoe doesn’t feel terribly fast, but it isn’t clunky either.

  • 79 / 100 | Believe in the Run | | Level 5 expert

    The outsole is sooooo thick you don’t need to worry about getting jabbed by the occasional sharp stone. 

  • 78 / 100 | Running Competitor | | Level 5 expert

    The Fat Tire running shoe is designed to mimic a mountain bike tire rolling over terrain.

  • 90 / 100 | Endurance Review | | Level 3 expert

    The comfort is terrific, the tread is top notch, the soul/guts of the shoe are truly remarkable, particularly on the punishing downhills. Here’s a shoe that can take whatever you can dish out.

    Just like a properly pumped up bike tire, the shoe is fire and bouncy. In fact, it actually feels like it has an inflatable tube inside due to the Under Armour “Charged” midsole.

  • The Under Armour Fat Tire features the Michelin WildGripper outsole with aggressive lugs. The outsole design is inspired from the fat tire off-road bike that delivers reliable grip and traction especially on uphill runs.
  • The midsole of the shoe was also improved. It uses the Charged cushioning foam that delivers impact protection and rebound. This works perfectly with the bottom-loaded foam that delivers added comfort and underfoot protection.
  • The Fat Tire also features the Under Armour Strom1 technology. It uses the moisture-wicking fabric that repels water, keeping the foot drier even on slightly wet conditions. This gives the foot the necessary moisture protection without sacrificing the upper’s breathability feature.

The Fat Tire is available in standard running shoe length. This shoe has a wider forefoot, and it gives a snug fit in the midfoot and heel area. The toe box is in medium volume. This shoe can comfortably accommodate those medium-sized foot and those who have slightly wider foot.

The outsole unit of the Fat Tire is uniquely designed. It is inspired by the fat tire off-road bikes. It features the multi-directional lugs that gives reliable traction on varied terrains. It provides impressive cross-slope grip which is very necessary on steep terrain. This outsole compound, which is also present in the UA Fat Tire 3, is also made durable for long-term use.

The midsole of the Fat Tire uses the iconic Charged cushioning system that delivers durable underfoot protection, unmatched energy return and support. The Charged foam is engineered to deliver a softer cushioning for high rebound. The bottom-loaded foam is also strategically placed underneath the Charged foam to give additional underfoot cushioning. This cushioning system is really designed for underfoot protection and to efficiently convert landing forces to forward energy.

The upper of the Under Armour Fat Tire provides a breathable coverage. It uses high performance and durable outdoor textile. Aside from the comfortable feature, the upper built is durable enough to survive the toughest terrain. With the UA Storm1 technology, the foot is kept dry throughout the run. The Strom1 textile has the capacity to repel water without sacrificing quality.
