Who should buy the Under Armour TriBase Reign 4

Based on the benefits that it delivers, this Under Armour trainer is great for you if you are looking for a shoe that:

  • is stable enough to support lifting and other complex CrossFit exercises
  • is porous enough to let out heat during aerobic gym exercises
  • does not have a one-bootie construction, which sometimes makes it difficult to put the shoe on

Who should NOT buy this training shoe from Under Armour

Though helpful, the grooves in the outsole might expose the foam directly on top of them to dust, water, and other natural elements. Hence, outdoor usage must be avoided or kept at a minimum. Those who love working out outdoors are better off with the Reebok Nano X2 TR Adventure or the Reebok Nanoflex TR.

The Under Armour TriBase Reign 4 is also not meant for players with narrow feet. They are more comfortable with the Under Armour Project Rock 4.

Those who want a less clunky option are advised to check the Under Armour HOVR Rise 2.

The outsole is designed for agile movements 

Just like in basketball shoes, the outsole plays a crucial role in training shoes. In the case of the Under Armour TriBase Reign 4, its outsole has multidirectional coverage and players report that this allows the shoe to bite the floor well. The sole also has grooves that go with the natural flexions of the foot.

It must be noted here, however, that the grooves are carved into the outsole. This makes the foam areas directly above the grooves more reachable by wear-and-tear elements. To lengthen this shoe's life, it is therefore advised to keep your workouts indoors.

Don't worry, your feet can breathe in the UA TriBase Reign 4

Upper quality is one feature that can make or break a shoe. Many people abandon training shoes just because they feel too warm in them. The Under Armour TriBase Reign 4 makes sure that there is enough airflow through its mesh upper to keep the foot well-ventilated.

Separated tongue makes on-off quite easy

Tongueless constructions, sometimes referred to as one-bootie constructions, get rid of the bulk for a more streamlined look and feel. However, they sometimes leave the opening difficult to adjust. The UA TriBase Reign 4 veers away from this construction and goes for a separated tongue, making it a lot easier to put on and take off.
