Reebok Nano X1 Sizing

I feel this shoe runs true to size.

An 11 fits me perfectly – and this is my normal size in nearly every running shoe and cross trainer.

The Nano X1 has the appearance of being not as wide as the Nano X (in the toebox, specifically.)

That’s an optical illusion because the difference is strictly in the outsole.

This video explains in detail:

Overall, I’d say the Nano X1 has the same wide toebox – it’s just an optical illusion that the Nano X has more.

I say buy your normal shoe size – or whatever size you were happy with in the Nano X.

Reebok Nano X1 Training Shoe- Overview

Let’s dive right in and talk about this shoe.

We’ll start from the ground and work our way upwards.

Like all its predecessors, it uses a high-traction, all-rubber outsole.

Reebok Nano X1 Training Shoe Review (9) Outsole
The all-rubber outsole reminds me of tire tread – which is appropriate, because it offers great traction.

It’s flat – no deep lugs here – and is clearly made for maximum contact area with the gym floor.

What’s contained within the shoe holds one of the biggest updates.

The midsole in this shoe is made from EVA foam, and it is utilizing Reebok’s Floatride Energy cushioning system.

The midsole of the Nano X1 is using EVA foam – and it has noticeably more cushion than the Nano X. You can really feel the difference when running or sprinting.

That’s right, this Nano has improved cushion. And you can really feel it in the heel – especially when running and heel striking.

Here’s another big change that you can’t see directly – they’ve increased the drop to 7mm.

The drop, or heel to toe drop, is the height difference between your toes and heel in the shoe.

Most running shoes have a good amount of drop (10mm is common) because it helps with endurance.

Heel to toe drop is 7mm in the Nano X1. Works great for squats – and more.

More drop can also benefit those doing squatting movements – you know like the front squat, back squat, clean, and more.

With this increase in drop, I have found the shoe more pleasant to squat in.

Here’s the last big change. The upper is now Flexweave Knit (at least for this version of the shoe.)

Prior versions used a super-tough version of Flexweave.

Reebok Nano X1 Training Shoe Review (12) Flexweave Knit
The new Flexweave Knit upper is comfortable and looks good. A "Grit" option will be available later for those that want the ultimate in a tough upper.

But tough means weight – and we’ll see shortly they’ve lightened the Nano with the X1.

Flexweave Knit gives up some of the toughness – but gains comfort and breathability for it.

For those that want an ultra-tough upper on their WOD shoe – there will be a Flexweave Grit option available at launch – this will be more akin to the traditional Flexweave upper.

The shoe hs lost 2 ounces of weight also.

(That’s a HUGE improvement!)

The Nano X1 weighs in at about 12.1 ounces for US Men’s Size 11 shoe.

Reebok Nano X1 Training Shoe Review (14)
This shoe weighs 12.1 ounces (US Men’s size 11). That’s about 2 ounces lighter than the Nano X.

Where did the weight go? The shoe has lost much of the rubber protection wrap, the big, pillow-like tongue, and the Flexweave Knit upper is certainly lighter too.

Overall that was my biggest concern with the Nano X – it just kept getting heavier and heavier.

Here’s one thing that may concern some folks – the tongue is now very skinny, and less padded.

It doesn’t bother me, but the tongue is now quite minimal and skinny in the X1.

Seems ok to me, but just be aware of that.

The Nano X1 gains some lateral stability too – thanks to the large, stiff TPU skeleton that encases the heel.

Reebok Nano X1 Training Shoe Review (11)
This big TPU cage that comes up around the heel offers exceptional rigidity which should translate to better side to side support.

This is a good thing – as this shoe has to be focused on athletics.

Let’s now compare this shoe one on one to the Reebok Nano X, which was released in 2020.

Reebok Nano X1 Versus Reebok Nano X

I liked the Nano X. I have two pairs, plus the PR edition, the Froning, and the Nano X Unknown.

But, it had two key weaknesses – too little cushion in the heel, and it was getting heavier with every release.

I feel like Reebok has addressed both concerns in the Nano X1 – and made a shoe with broader appeal.

That said, with the release of the X1 you are going to be able to get a deal on the Nano X – and it’s still a great shoe.

Let’s compare them side by side.

Reebok Nano X1 Versus Nano X Training Shoe - Outsoles
Outsole versus outsole. THe Nano X used a de-coupled outsole and midsole to reduce shock. I’m not sure it really worked though – and it’s gone from the X1.

Both have a nice wide toebox. They are in the same ballpark, but the Nano X looks a tiny bit wider – because the outsole is wider – it doesn’t impact the room for your toes.
Reebok Nano X1 Versus Nano X Training Shoe (5)
Both have a very stable and supportive heel and are great for heavy weightlifting. The added bonus of the X1 is that you get some cushion for running – but not so much that it ruins the firmness for barbell lifts.

Comparing the two heels side by side. I feel like the X1 with the TPU external frame will give better lateral support.

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

I think you’ll shortly be able to find a lot of good deals on the Nano X – but if you are into impact activities and running – I’d go with the X1 instead.

Reebok Nano X1 Training Shoe Review – In Summary

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

Reebok has dropped the singular focus on CrossFit, and made a shoe with wider appeal in the process.

It’s lighter, it has some drop (7mm), and perhaps best of all – there’s actually some cushion in the heel now.

The Nano just got a whole lot more versatile with the Reebok Nano X1.

What’s the verdict? This shoe is a winner. They’ve improved on the weaknesses of the Nano X and come up with something better.

Reebok Nano X1 Training Shoe Review (13)
I like the fit and feel of this shoe and the new external TPU frame around the heel means super-stability.


  1. I can’t comment if they won’t last as long – as I’ve only had both a few weeks. The Knit is still pretty tough, it’s not a soft, sock-like knit like Nike uses on FlyKnit. That said, the Grit upper is definitely going to be longer lasting – in regards to abrasion of the upper. Honestly the knit doesn’t feel less stable to me either, because it’s all on the top of the shoe.

  2. differences and advantages of taking the breathable model (Flexweave® knit)
    do they last less and are they less stable?

  3. having less sole, is it less stable in lateral movements? I am very interested in stability in lunges or similar exercises with the legs, with one leg etc, even lateral exercises etc etc

  4. thanks you are very kind. I don’t speak English well what does it say in the video summarizing?

  5. is it possible to know with a meter if it is really less wide? I have a wide foot but honestly looking from the outside the shoe looks much smaller, it would be a useful thing to know for us wide feet haha

  6. Exterior dimensions seem to be the same, but it feels like there is SLIGHTLY less room in the Nano X1. That said, I’m very happy with the Size 11 I bought – which is the same size as all my Nano X (I have several pairs).

  7. I did not understand if the toebox seems smaller or is it really smaller, I have a wide foot, the version with more solid fabric weigh more?
