The Under Armour TriBase Reign's outsole

The Under Armour TriBase Reign features a full-length rubber outsole. It is hardwearing to prevent an early breakdown of the midsole. The TriBase technology refers to the three zones of the outsole. The forefoot features flex grooves that help with the upward and downward movements of the feet.

Anti-toe slippage

The construction of the rubber under the toes intends to prevent slipping during push-ups and burpees. As for the sides of the TriBase, they aim to aid in torsional flexing that happens during quick lateral cuts.

Abrasion-resistant components

The rubber wraps the medial and lateral sides of the shoe at the midfoot. This element protects the midsole and a section of the upper from abrasion during rope climbs.

Enhanced platform stability

This pair of Under Armour training shoes is equipped with the Micro G midsole. This foam technology is manufactured to be 30% thinner than the conventional foam to deliver a low-to-the-ground disposition which helps in keeping the foot stable.

Despite its thin appearance, its shock attenuation properties are similar to those of thicker platforms. It compresses but quickly bounces back to its original form for an explosive take-off. The 2-mm offset positions the heel only slightly higher than the ball of the foot. This low elevation is common for CrossFit shoes because it helps keep the rearfoot steady, especially during weight training.

Inside the trainer is a non-removable insole. It prevents slippage and enhances the shock absorption of the midsole.

Ventilated upper

The Under Armour TriBase Reign employs the ripstop material for its upper. Ripstop is a type of fabric that has reinforcement threads interwoven into it at regular intervals to make it tear- and rip-resistant. The forefoot and the lateral quarter use a durable mesh with abundant perforations to keep the interior ventilated.

The Under Armour TriBase Reign's overlays

Synthetic overlays line the toe box, the eyestay, and part of the medial side of the midfoot. They amplify the durability of the underlying fabric to prevent it from disintegrating quickly.

Snug lacing system

A lace-up closure allows users to adjust the midfoot fit. It does not have a plush interior, but the upper is crafted to mold onto the feet for a secure foothold.

Stabilized rearfoot section

There’s a plastic component that is attached at the heel and rises to about a third of the rearfoot. It acts as an external heel cup that keeps the back of the foot steady during dynamic movements.
