Under Armour TriBase Reign 3 Review | Great for Lifting?

The Under Armour TriBase Reign 3 is the latest cross-training shoe from Under Armour to hit the mass market. This model is the third edition in the TriBase line and Under Armour has levelled up this cross-training shoe with new construction features once again.

Compared to the Under Armour TriBase Reign 2, I really enjoy the performance of the TriBase Reign 3. Don’t get me wrong, I like the TriBase Reign 2, but the Reign 3 feels much more intent-driven and it has some key upgrades that I love to see in serious cross-trainers.

In this review, I dive into the details that make the Under Armour TriBase Reign 3 one of the better cross-training shoes to rock in 2021.

Under Armour TriBase Reign 3 Pros

There are three key aspects that I really like about the Under Armour TriBase Reign 3 cross-training shoe.

  1. Reworked Upper Construction
  2. Outsole and Midsole Construction
  3. Overall Fit and Feeling

The first thing that I like about the Under Armour TriBase Reign 3 includes the reworked upper construction. Compared to the Reign 2, the Reign 3 has a reworked mesh with a synthetic material on top to increase the overall durability of the shoe. On top of an increase in durability, this material also provides this model with a lightweight a breathable feel.

The second construction and performance aspect that I like about the Reign 3 is the outsole and midsole construction. The outsole has Under Armour signature TriBase construction which provides an awesome stable base for creating a tripod foot position. In addition, the Micro G Foam midsole and zonal flex construction in the forefoot add a nice layer of responsiveness to the overall stability of this shoe.

The third detail that I enjoy about the Reign 3 is the overall fit and feel when working out. This model feels light on the foot and it fits fairly “athletically”, meaning it has a slightly more narrow build to it and feels/performs like a sport-focused shoe which is an awesome thing for both lifting and agility/plyometric work.

Under Armour TriBase Reign 3 Cons

There are two potential cons that I could see other lifters and athletes having with this model.

  1. Narrow Fit
  2. Bootie Design

The first potential con is how this shoe will feel for those with wider/flatter feet. The Reign 3’s last is slightly more narrow in nature through the midfoot and I could see my wider footed friends having an issue with the overall comfort of this model especially around the transitional area between the toe box and midfoot.

The second potential con I could see lifters and athletes having is not enjoying the bootie design. Some lifters and athletes love bootie constructed shoes and others are not the biggest fans. This model does have a bootie design, so if you’re someone who loves having a separate tongue and boot construction, then you may not like the Reign 3 as much as other cross-training models.

Performance

All-in-all, I was a fan of this shoe’s performance in the gym and during plyometric/agility focused workouts. In this section, I’ll breakdown the Under Armour TriBase Reign 3’s performance into three sections including lifting, agility/plyometrics, and day-to-day wear with shorter runs.

Lifting

In regard to lifting, I think most lifters will really enjoy this model. The 2mm heel-to-toe offset provides a very low-to-the-ground feeling and stable base under a variety of loaded movements. On top of that, as mentioned before, I think the outsole and midsole construction does a really good job of walking the line between stability and responsiveness during workouts.

The forefoot construction allows you to get on the toes really easily when moving through triple extension and the overall construction of the outsole grounds the foot really well.

Agility and Plyometrics

Whenever a cross-training shoe has a more “athletic” fit and feeling to it, then you can assume it’s usually a good option for agility and plyometric focused work. The upper in the TriBase Reign 3 is very maneuvrable and the Micro G Foam midsole does a great job at providing responsiveness for most athletes and lifters training in this realm with this shoe.

Additionally, I personally like the bootie design of this model and it plays well into the lightweight nature of the shoe.

Day-to-Day Wear and Shorter Runs

On a day-to-day basis, this shoe does okay. To be honest, it’s not my favorite model for long periods of wear and the narrow midfoot can be slightly uncomfortable when worn for longer durations. It’s not a make or break when it comes to performance and shorter wear times, but its something to consider based on how you plan to wear this model.

under armour tribase reign 3 sizing and fit

For shorter runs (<3 miles) this model will work fairly well, and I think it’s a decent model for short sprint-focused work and faster-paced tempo runs. When it comes to long runs, I would say look for other options to rock as I could see this model being uncomfortable when putting in high amounts of mileage.

Sizing and Fit

The TriBase Reign 3’s sizing and fit are really interesting. I think the vast majority of lifters and athletes should go true-to-size in this model. However, if you are someone with a wider foot and you’re solid on the TriBase Reign 3, then it might be worth going up a 1/2, but I would highly recommend trying this model on first if this sounds like you.

Price

For a brand new pair of Under Armour TriBase Reign 3s, you can expect to pay $120 USD. This price is similar to previous models and is comparable to other cross-trainers on the market. It’s actually $10 USD less than most popular, new cross-training shoes.

UA TriBase Reign 2 Vs TriBase Reign 3

There are a lot of similarities between the UA TriBase Reign 2 and TriBase Reign 3 training shoes. For example, their midsole and outsole construction are both similar and they offer comparable levels of stability. In addition, both models feature a 2mm heel-to-toe drop and have a very “low-to-the-ground” feeling.

The main difference that’s worth noting is the reworked upper construction in the TriBase Reign 3. This model’s upper is what I would call a level up and features a much more durable-focused build.

Are the Under Armour TriBase Reign 3s Worth It?

Personally, I really enjoy the Under Armour TriBase Reign 3s. Compared to the first model, you can tell that Under Armour has been listening to their consumers and making changes based on the feedback they receive.

If you love having a lower heel-to-toe offset (2mm) in your cross-training shoes and like athletic-fitting models, then I definitely think the Under Armour TriBase 3s are worth it.

Under Armour TriBase Reign 3 FAQs

Can you run in the Under Armour TriBase Reign 3s?

The TriBase Reign 3s work for shorter runs and sprint work fairly well. However, this is not the best model for longer runs as it can be fairly uncomfortable at times. If you plan to run more than 3-mile bouts, then you may want to look at dedicated running shoes.

Can you do HIIT in the Under Armour TriBase Reign 3s?

Yes, the TriBase Reign 3s do a great job when tackling HIIT workouts. The Micro G Foam midsole provides a nice level of responsiveness during various activities and the TriBase outsole provides a nice level of stability. In addition, the 2mm heel-to-toe offset gives this model an edge with multi-directional workouts.

Are the Under Armour TriBase Reign 3s a slip-on shoe?

The TriBase Reign 3s have a bootie construction so there’s no separate tongue and there is some level of “slipping on” this model. However, there are 5-eyelets running up the mid-foot which provides a nice level of security and they make this model not a true slip-on.

Can you lift heavy in the Under Armour TriBase Reign 3s?

Yes! This model provides a low 2mm heel-to-toe offset which gives this model a very low-to-the-ground feeling and the additional plastic heel cups really helps ground the foot. In addition, the Micro G Foam midsole and TriBase outsole do a good job at preventing compression under various loads.
