Bottom line

The Fat Tire Low is the Low Top version of the standard model. It has loads of traction on almost all types of outdoor surfaces, including wet surfaces. For a pretty steep price, runners get tons of comfort and unbelievable protection against the sharpest objects on the trail. While this may not be the best option for long runs or technical running, the shoe is unbelievable for short distance forays on the most challenging trails that do not require agile movements.

    So far, I'm doing really great! I love the cushioning; it's just amazing. I think I have now a new favorite.

    The heavily cushioned shoes in combination with the Michelin sole were great when traversing ground with smaller rocks as I hardly noticed the sharp uneven edges.

    I would highly recommend these shoes to anyone that is looking for something more comfortable and is fine compromising on weight for that extra comfort and support. I’m a little on the “bigger” side compared to most elite runners so I really like having a shoe that has more cushioning to it like the UA Fat Tire.

    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.

  • Under Armour’s association with giant tire manufacturer Michelin is a huge development in the Fat Tire Low. The patented blend of tire-inspired lugs and sticky rubber compound easily place the shoe as one of the best where traction is concerned. Under Armour also enhances the outsole durability with this exciting union.
  • The thick outsole also works doubly as the main protection against sharp objects. Runners should be able to run over rocks and pointed things without any inhibition in this shoe.
  • The seamless upper hugs the foot in comfort and security. It has water repellent features designed for light drizzles or runs in the evening or early morning.

The fit of the Fat Tire Low is just like the standard version. It has decent space in the heel and midfoot with quite a roomy toe box. Runners with a little extra requirement in the forefoot will love the fit of this shoe. The heel and midfoot are adequately secured when running on rugged trails. It runs true to size.


Michelin elevates the traction and durability of the outsole with their proprietary technology and underfoot lug system. The lugs are moderately aggressive and are found all over the shoe. It provides excellent bite on all surfaces and has the added bonus of preventing loose trail or mud from sticking to the outsole. A sticky rubber compound gives it excellent traction while harder rubber in the heel and other areas improve durability. The outsole of this shoe is as durable as the Cascadia 13 trail shoe.


A stick slice of Charged Cushioning spans the midsole of the Under Armour Fat Tire Low. It provides an almost cloud-like cushioning and unbelievable protection at the same time. The full-length structure makes transitions easier and quicker.


A water-resistant mesh that is still breathable forms a big part of the upper. There are bonded overlays on both sides of the foot for seamless support and security. A thicker welded overlay in the forefoot acts as the sufficient toe bumper. An Ortholite sockliner is included for its moisture-wicking and anti-microbial properties. A traditional lace-up closure clinches the fit in the Fat Tire Low.
