  • The Fat Tire 2 utilizes the same outsole and midsole as its previous version. It only features several updates in the upper for an enhanced running experience.
  • One noticeable update in the upper is the ankle collar cleatie construction. It wraps the ankle comfortably and provides additional support. It also serves as a shield against dirt and trail debris.
  • Another update is the Boa® Closure System that provides a precise fit and comfortable feel. This closure system locks your foot securely in an easier, quicker, and tighter manner compared to the ordinary laces.

The 2nd iteration of the Fat Tire available in a standard medium width for men and women’s version. It has medium measurements in the heel, mid-foot, and forefoot, giving users with medium foot shape a nice and comfortable fit. The shoe fairly runs true to size.

Just like the previous version, the Under Armour Fat Tire 2 utilizes the Michelin® Wild Gripper outsole rubber compound. This premium outsole technology is inspired by tires used on big bikes. It has multi-directional lugs that are designed for unmatched grip on various terrains.

The shoe features the Under Armour Charged Cushioning® in its midsole. It provides durable underfoot cushioning that efficiently absorbs impact during landing. It also provides a high-energy return for a more responsive ride. This midsole material is also present in the Fat Tire 3 trail shoe.

The Under Armour Fat Tire 2 makes use of a new ankle collar cleatie construction that is specifically designed to provide ankle support. It also gives protection to the foot against mud, small stones, and other trail debris.

Along with the ankle collar construction is the Boa® Closure System. It uses a micro-adjustable dial with durable and lightweight laces. This lacing system aims to provide a precise and long-lasting fit.

The shoe utilizes a soft-shell material in its upper. It is flexible and lightweight material that provides the foot a comfortable coverage. It also has a tough rubberized print that provides durability to the upper.

The Fat Tire 2 also uses the Under Armour Storm™ technology. It is a lightweight fabric with a Durable Water Repellent (DWR™) feature. It helps repel water while running in wet conditions, keeping the foot dry all throughout the run.

To keep the foot odor-free and free from fungus, the shoe makes use of the Cupron® Anti-Fungal Pro Fibers sockliner. The fibers are engineered to reduce odor and kill 99.9% of athlete's foot fungus.
