Here’s the Nano X1 with the Flexweave Grit upper. In the background is the Nano X.

Our review pair has arrived and we’ve put them through our workout test – side by side with our trusty pairs of Reebok Nano X.

Before we dive into the results, let’s review some of the shoes that are available now:

Nano X1 Men's Training Shoes (Black/True Grey 8/Pewter) This is the "I'll Call You Back" edition - and it is available now. It's sporting a subtle and dark color theme. This is the style seen in most of the photos in this article.
Nano X1 Grit Men's Training Shoes (Grey/Core Black/Orange Flare) This is the Grit upper - it's tougher than the knit upper, and is more like the Flexweave of years past. There's no weight penalty though - this shoe is just as light as the knit version.
Reebok Nano X (Cool Shadow/Black/White) Men's Training Shoe in Cool Shadow/Black/White.
Reebok Nano X Unknown (Pure Grey 5 / Black / White) With these men's mid-cut shoes you'll be ready. The textile upper and high collar provide extra coverage and support. Added midsole cushioning and a decoupled outsole make them more comfortable than ever before. This is the colorway shown in most of these photos.
Nano X Froning (Men's - Black / White / Reebok Lee 7) Known as The Fittest Man in History, Rich Froning Jr., joins the Nano franchise with these men's shoes. They were designed to fulfill all the needs of an elite athlete. Coming July 21st - these WILL SELL OUT!
Vertex Micro Crew Ultra-Light Cushion (Darn Tough) You know what kind of sock works best with a lightly cushioned cross trainer like the Nano X? Get a running or athletic sock with some padding in the heel and forefoot - like these from Darn Tough. Merino wool/Nylon/Lycra Spandex - made in the USA

Let’s compare these two cross training shoes for CrossFit.

That’s some in action video of the Nano X1 – but let’s dive deeper into all of the details.

Reebok Nano X1 Versus Reebok Nano X – Sizing

Here’s my thoughts on size.

The Reebok Nano X shoe runs true to size, just like the Nano X did.

A US Men’s Size 11, which is my normal shoe size for most trainers and running shoes, fits perfectly – in both shoes.

The width is excellent, the length is good, and overall these are comfortable.

There’s one caveat – the new comfort collar in the Nano X1 does put some pressure on the top of your heel.

Here’s a picture that compares the heel of both – notice how the X goes straight up, but the X1 curves inward.

Here’s one factor in fit and comfort. The Nano X had a straight vertical heel, where as the new comfort collar on the X1 curves inward. It may put pressure on the back of your heel/ankle.

Will this break in over time? I’ll provide an update here in a few weeks.

The other big thing we need to address is the optical illusion that the X1 is less wide than the Nano X.

How about width? The Nano shoe has had legendary toe box room in the past. But now the shoe looks to be not as wide?

Reebok Nano X Grit Versus Reebok Nano X
The outsole is slightly wider on the Nano X – but the space in the upper for your toes is the same, in my opinion.

In a nutshell, the outsole is narrower, but not the actual area in the upper that accommodates your toes.

The all-black color is the X1. Both have a nice wide toebox. They are in the same ballpark, but the Nano X feels a tiny bit wider.

So really, it’s sort of an optical illusion. This video explains in detail:

Reebok Nano X1 Versus Reebok Nano X – Overview

Let’s switch gears and talk about performance differences now.

There are really 3 big changes with the X1.

It’s significantly lighter than the Nano X. This holds for both the knit upper and the so-called Grit upper.

Reebok Nano X1 Versus Nano X Training Shoe (6)
First big difference – the X1 is 2 ounces lighter than the Nano X.

How much lighter is it? A US Men’s Size 11 Nano X1 weighs 2 ounces less than a similar-sized Nano X.

Is the Nano X1 as tough and durable? Only time will tell.

It definitely feels less tank-like as compared to the Nano X.

I do recommend you go with the Grit upper, because it’s tougher, and it looks better – in my opinion.

Reebok Nano X1 Grit (6)
The Grit upper is probably your best option for a tough shoe. It seems like it will be more robust than the knit upper (which isn’t too weak by the way.)

Here’s another BIG difference – the X1 actually has some cushion to it.

That’s right, Reebok has dropped their Floatride Energy system into the forefoot, and the shoe uses an EVA foam midsole.

The X1 has noticeably more cushion in the heel and midfoot than the X. It’s hands down better for running and impact.

Reebok claimed the Nano X was “runnable” – it wasn’t, in my opinion.

It had so little cushion (especially in the heel) that running on any sort of hard surface like asphalt or concrete was quite unpleasant.

Now, to be clear, the X1 isn’t a running shoe. It’s a cross-trainer.

The Nano X1 has a fairly stable heel – but it’s not as stable as the X. The X is the better heavy strength training shoe.

They’ve added cushion, but they haven’t eliminated the ability to lift heavy with barbells (or kettlebells, dumbbells, etc.) in this shoe.

Having said that – the Nano X is more stable under heavy weights. There’s just not very much cushion for your foot to sink into.

Here’s one thing that you may like about lifting weights in the X1 – it has 7mm of heel to toe drop.

That little bit of extra drop, 3 mm more than in the Nano X, makes it a little bit easier to go deep on a squat.

Reebok Nano X1 Grit (28)
The Nano X1 has 7mm of heel to toe drop. The Nano X has only 4mm.

(Or anytime you are lifting the barbell up off the floor.)

That extra bit of drop should help for long-distance endurance too – thinking running or standing all day.

Style counts too.

Ultimately, I think you need to determine – does the shoe fit you well, and how does it look?

(That’s something only you can decide.)

Reebok Nano X1 Versus Reebok Nano X – In Summary

That’s our review of the Reebok Nano X1 Training Shoe versus the Nano X.

Reebok has dropped the singular focus on CrossFit, and the X1 will have a wider appeal to fitness enthusiasts.

The X1 is 2 ounces lighter, has 3 mm more of heel to toe drop, and has better cushioning.

Overall, I think the Nano X1 is a better shoe for impact activities and sprinting or running – but you can still lift weights in it.

The Nano X has minimal cushion (and drop) but feels super-stable in heavy barbell lifting.

That all being the case – there’s something to be said for style and how well the shoe fits you.

The Floatride Energy system is a good thing if you do impact exercises.

Flexweave Knit versus Flexweave. We’ll have to wait and see if Flexweave Grit is just as tough as that on the Nano X.


  1. For someone getting into weight lifting for the sake of cutting (not bulking) which would you suggest between the 2? I would only really be using these shoes for weightlifting, not any other exercises.

  2. The X is more stable, but more so because it doesn’t have the stack height that the X1 does. The X1 has a taller, softer heel.
