Here’s the 3rd version of UA’s TriBase Reign cross training shoe. It’s a mild refresh of the TriBase Reign2 – with some tweaks. Read on to find out more…

The Under Armour TriBase Reign is UA’s first committed cross-training and functional fitness shoe. It is made of quality materials that can survive grueling workouts. It is a very competent training shoe that will help you keep up in the training game. A year after the launch of the TriBase Reign 2, UA now introduces TriBase Reign 3. Let’s see what the upgrades are from the former.

Here are some of the styles that are available now:

TriBase Reign 3 Training Shoe – Overview

Here’s the summary – this is a minor revision to last year’s shoe.

The upper is new, the heel counter is tweaked, but otherwise, it’s the same outsole, midsole, and overall shape and size.

As such, that’s OK – because this is a good CrossFit training shoe – just like the TriBase Reign 2 was.

The 3rd version of the TriBase Reign training shoe from UA is here. Of course it has the TriBase…

The outsole of TriBase Reign 3 continues to use Under Armour’s signature TriBase structure, which is intended to better ground contact and stability from a platform foot position. It uses a rubber material and does its job of holding compression when under heavier weight. This material boosts strength at the bottom of the big toe, little toe, and heel’s start.

There are not too many big differences from the TriBase Reign 2, but the upper certainly is one of them.

The new mesh upper of the TriBase Reign 3. It has tough print on top of the mesh strategically placed.

Here’s a good example where the extra print on top of the mesh upper is placed to help defeat any friction the upper might get.

It’s a mesh-like upper – and it provides a close, comfortable fit. It’s stretchy in sock-like fashion up around your ankle.

This upper is comfortable and stretchy and gives a very close fit.

The previous shoe had a mesh upper too, but not as nice as this one. Even better, they’ve added some sort of 3D Print on top of the mesh for toughness.

This harkens back to another cross-training shoe – the Nike Metcon 4. Check it out here. Seems like UA used this idea for inspiration – and that’s good because I feel like the Metcon 4 was a true classic. It was light-weight and tough.

Did you like the 3D print on the Nike Metcon 4? The new upper on the UA TriBase Reign 3 is similar.

Reign 3 has an engineered mesh upper with a knit bootie structure and overlays for added stability and abrasion-resistance. The upper is durable and also relaxed and spacious, particularly in the toe box area. The external heel counter and close-fitting collar present enough balance at the rear of the shoes.

The heel counter has been tweaked. It’s still tough (and slick) TPU, but they’ve added a knife edge to it – probably to help reduce friction against the while when doing HSPUs.

Drop is still 2mm. THat’s low-profile, even by cross-trainer standards.

The full-length Micro G foam midsole does an excellent job in decreasing impact force, and it is ready for any twist and turns you want to do in it. TriBase Reign 3 is very flexible, and you won’t slip in it while doing barbell snatches and box jumps or even planks and mountain climbers. It has a low-to-the-ground frame allowing greater feel and power transfer.

Here’s a side profile view. Drop is 2mm. The midsole uses UA’s MicroG foam.

There’s a small wrap-around section at the midfoot too – to assist in toughness (and grip) for rope climbs.

Tough rubber outsole wraps around at the midfoot for rope climbing grip and friction protection.

UA TriBase Reign 3 – Sizing

Like the UA TriBase Reign 2, these are true to size.

I ordered my normal running shoe size (US Men’s 11) and it fits great. Both width and length are good.

Here’s that TriBase. These are true to size. I advise you order your normal running shoe size – that’s what worked for me.

As such, I recommend you order your normal shoe size.

UA TriBase Reign 3 – In the Gym

How does it all work?

It feels very, very similar to the UA TriBAse Reign 2.

That’s expected because the sole and midsole are the same.

With a low drop this is a good, versatile training shoe.

It’s fine for all the things you would typically do in a CrossFit WOD or other functional fitness style training.

To test these, I did box jumps, burpees, short runs, rope skipping, lifting, and more.

Being a cross-trainer, these have minimal cushion.

That’s great for lifting heavy barbell weights, but less great for running.

You certainly can run in these, but I would not run very far. I personally need a shoe with more cushion for running.

Outsole and midsole are the same. Identical levels of cushion.

TriBase Reign 3 Training Shoe Review – In Summary

That’s our review of the TriBase Reign 3 Training Shoe from Under Armour.

Under Armour took another step ahead into the functional training demographic with Tribase Reign 3. It is very cozy to wear, grants loads of traction, and lets your foot flex naturally. It is not a flashy shoe, but you will be able to perform well with it.
