The Reebok Speed 21 TR is a lightweight cross-training shoe designed for tackling HIIT workouts, classes, and other recreational forms of lifting.
This model features a breathable upper construction and Floatride Energy Foam midsole to provide it with a high level of responsiveness. After reviewing countless Reebok CrossFit and cross-training shoes, I was curious, where does this model fit into serious training?
The Reebok Speed 21 TR feels somewhat similar to the Reebok Nanoflex TR but has construction elements that somewhat resemble the original Reebok Nano X1.
Who Should Buy the Reebok Speed 21 TR?
The Reebok Speed 21 TR is not going to deliver you the same stability that you’d get from the Reebok Nano X and Nano X1 models, but it will do an okay job for recreational lifting.
This shoe’s Floatride Energy Foam midsole is highly responsive and provides a decent amount of ground feedback for things like plyometrics and HIIT training.
If you constantly tackle HIIT workouts and take classes like F45 and want a shoe for primarily lighter lifting and more athletic-focused training, then I think the Reebok Speed 21 TR is a good pick. The only drawback is the long-term durability of the laces, which we’ll discuss below.

Reebok Speed 21 TR Pros
Over the course of my training, there are three key pros that really stood out to me with the Reebok Speed 21 TR.
- Lightweight Upper Construction
- Lug Outsole Pattern
- Lightweight Build and Responsive
The first aspect to like is the upper construction. The Reebok Speed 21 TR features a breathable mesh which is huge for what this is designed to do. If you’re training in a class or even in an athletic-focused setting where you’re outside or in a hot gym, you want your shoes to breathe and this model does a good job at tackling this task.
Another pro to this shoe is the lug outsole pattern. The lug pattern on this model is pretty much the same exact patterning used on the Reebok Nano X1. In regard to traction and gripping the floor, I’m a huge fan of this lug patterning so I was super excited to see it used on this model.
The last aspect to like about this model is how responsive the midsole is and the weight of the shoe. The Floatride Energy Foam midsole provides a nice level of “bounce” to the forefoot when doing bounding activities and you get a fair amount of energy feedback from the ground in this model.
On top of the responsive midsole, the overall weight of this shoe is also pretty stellar. At a weight of 10 ounces for a size 10 model, this is certainly one of the lighter Reebok cross-training shoe options you can get.
Reebok Speed 21 TR Cons
While I do enjoy training in this shoe, there are a few durability concerns that I have for its long-term use.
- Eyelets Fall Short
- Skinny Tongue Moves
- Leather Toe Wrap Feels Odd
The first con with the Reebok Speed 21 TR is the eyelet construction. While I like the idea behind the lighter loop eyelets, their durability just isn’t there. It doesn’t take a ton of force to pop the top two eyelets which could be big a fairly big problem for those who will be doing a lot of jumps and running in these shoes.
Basically, as we drive into the ground when training and move into a more dorsiflexed position (toes flexed up), that force produced into the ground and mitigated through the upper portion of the ankle into the shoe could lead to the eyelets popping or breaking down fairly quickly.
Another aspect to be conscious of is the skinnier tongue on this model. The tongue wouldn’t be an issue if it had a tongue loop that the laces could go through to help lock it down. Without the loop, the tongue slides a tiny bit if you don’t lace the shoes fully and tightly.
The last thing that I’m not too fond of on these shoes is the synthetic leather toe wrap. Personally, I feel like it doesn’t fit the lightweight design and construction of this model and it seems a bit excessive. This is me nitpicking, but why couldn’t they use a lighter material to boost toe box durability?
Reebok Speed 21 TR Performance
For this performance section, I’m going to break the Reebok Speed 21 TR’s performance into three key sections including lifting, HIIT-style training, and shorter runs/daily wear.
Lifting
If you want to lift in this model, then I’d suggest capping your loading to about 315-365 lbs. Anything more than that and you’ll start to experience some compression in the Floatride Energy Foam midsole. When pulling 405 lbs, I felt the shoe compress a bit in the toe box.
For recreational lifting, this model will work just fine. So, if you plan to use kettlebells, lighter dumbbells, and more static strength work, then you should be just fine in this model. It won’t be the best for heavier barbell work, however, that’s now what it was designed to do.
HIIT, Plyometrics, and Agility
For HIIT-style training and athletic-focused work, this model was pretty awesome. It delivers the outsole traction from the Nano X1 and the lightweight budget-friendly versatility of the Nanoflex TR. Compared to the previous Speed TR, the Speed 21 TR is really different and it’s interesting seeing the shift in construction in this model.
The Floatride Energy Foam midsole provides a lot of pop to this model and the lightweight mesh feeds really well into keeping this shoe lightweight on the foot. Whether you’re jumping or performing agility work, you shouldn’t feel like this model is slowing you down and the wider outsole construction provide a nice base to plant and drive from.
Shorter Runs and Daily Wear
If you plan to run in this shoe, then you should be pretty safe taking them out for shorter mileage bouts. For example, if you’re tackling three miles or less, then this shoe should work pretty well. Note, it has a 3mm heel-to-toe drop so it will definitely favor those with a mid-foot strike a bit better.
On a daily basis, this model is comfortable and fine, but I’d suggest actually limiting their daily use if you want them to last. They already have some durability issues across the board and if you want them to last, then you’d be better off only limiting their wear for the gym.
Reebok Speed 21 TR Sizing
For most lifters and athletes, you should be safe going true-to-size in the Reebok Speed 21 TR. The length fits true and overall this shoe has a more “neutral” mid-foot fit and width.
Staying true to other Reebok Speed TR models, it is worth noting that this shoe’s toe box and mid-foot aren’t the widest. If you have a flatter foot, then you may be better suited looking into other training shoes that have slightly wider lasts.
Price
For the Reebok Speed 21 TR, you can expect to pay $100 USD. To be completely honest, I’m torn on this price. I think the price point is decently cost-efficient for what this shoe is designed to do, but the durability makes me pump the breaks.
If you can get away without popping eyelets in this shoe, then I think the price is fair. Personally, I feel like the eyelets will be the biggest issue for those with higher arches and thicker feet where they’ll be placing more stress into the upper portion of this shoe.
