But with the launch of the Nano X4, you might be wondering: how does it differ from the other shoes in the Nano range, like the Nano FX? Wonder no more, here at The Sports Edit, we break it down so you can make the best choice for your workouts.

Reebok Nano X4

It's no secret that Reebok has long been a trailblazer in the world of athletic wear, pushing boundaries and constantly innovating to keep up with the evolving needs of athletes. The Nano series, in particular, has earned its stripes thanks to its performance-driven design and unmatched durability, establishing itself as a staple choice for gym-goers and CrossFit enthusiasts alike. Let's break down the individual styles:

Nano X4

The Nano X4 is the new kid on the block in Reebok's Nano line, packed with a load of updates and enhancements aimed at elevating your training sessions. With a primary focus on being a master of all trades, the Nano X4 is meticulously engineered to excel across a spectrum of workouts, ranging from heavy weightlifting sessions to high-intensity interval training.

Nanoflex TR 2

Before the Nano X4 came onto the scene, the Nanoflex TR 2 held down the fort as the favourite, thanks to its lightweight build and responsive cushioning. While the Nanoflex TR 2 continues to hold its ground as a reliable option for gym workouts and agility training, the Nano X4 introduces several game-changing features that set it apart.

One standout difference between the Nano X4 and the Nanoflex TR 2 is the introduction of the Free Range Movement platform. This revolutionary technology delivers enhanced flexibility and stability during dynamic movements. Additionally, the Nano X4 features a redesigned upper, complete with breathable mesh panels, keeping your feet cool so you can power through your workout.

Nano FX

On the flip side, the Nano FX stands as another much-loved member of the Nano family, standing out for its reliable performance and unwavering durability. Crafted with a robust design and a supportive fit, the Nano FX caters to athletes who prioritise stability and support in their training footwear.

Key Differences

Despite looking similar on the outside, it's the differences between the styles that set them apart. As they target different activities, it makes it easier to choose the right fit for you. Mainly, they can be categorised based on their design, performance, and comfort.

Design and Construction

When it comes to design and construction, the Nano X4 oozes a sleek and contemporary aesthetic, characterised by its low-profile silhouette and seamless design. In contrast, the Nano FX adopts a more conventional design approach, featuring a slightly bulkier profile accentuated by structured overlays that provide added support and stability.

Performance and Versatility

While both deliver outstanding performance and are ideal for a wide range of activities, the Nano X4 stands out thanks to advanced technologies such as the Free Range Movement platform and strategically positioned breathable mesh panels. These thoughtful additions make the Nano X4 better at accommodating dynamic, multi-directional movements.

On the other hand, the Nano FX shines when you need stability and support, making it ideal for grounding you during workouts that include weightlifting and strength training.

Comfort and Fit

In terms of comfort and fit, the Nano X4 gets the gold star. Its lightweight design and adaptive cushioning make it ideal for rapid movements, so you never feel weighed down. The Nano FX, while undeniably comfortable, can feel a bit more rigid and flat due to the structured overlays and snug fit.

Ideal Workouts for Each Style:

If you're still not sure which style to go for, it might be helpful to consider what workouts you do the most. While they're both super at supporting every workout, subtle differences based on your personal flow can make all the difference.

The Nano X4 stands out for its emphasis on flexibility and agility, attributes ideal for dynamic movements and high-intensity workouts. The advanced design interweaves strategically placed ventilated mesh panels, promoting airflow and enhancing breathability to keep your feet cool during intense activities like high-intensity interval training (HIIT) and plyometrics. Additionally, the Nano X4's Free Range Movement platform is engineered to deliver unparalleled flexibility, facilitating explosive plyometric movements with minimal restriction, empowering you to push your boundaries and achieve peak performance.

In contrast, the Nano FX prioritises stability and support, catering to athletes focusing on controlled movements and secure footing, especially during heavy lifting sessions and strength-focused exercises. Its sturdy construction and snug fit provide the stability required to maintain proper form and reduce the risk of injury for added confidence and safety throughout your workout. Additionally, the Nano FX's heel stabiliser reinforces your form, particularly beneficial for activities involving lateral movements and quick changes in direction, such as CrossFit workouts that demand agility and stability in equal measure.

Whether your routines focus on agility and responsiveness for dynamic movements (Nano X4) or favour stability and support for controlled motions (Nano FX), selecting the right style can enhance your performance during workouts.


In short, both the Nano X4 and the Nano FX are stellar choices if you're looking for performance and durability, earning their status as worthy contenders in the footwear arena. Whether you need to focus on agility and versatility or stability and support, Reebok's Nano series offers an array of options to suit your preferences and tailored to your needs.

So, which model is right for you? Ultimately, the answer to this is as unique as you. If you engage in workouts that demand agility and adaptability, you might lean towards the Nano X4. On the other hand, if stability and support take precedence, the Nano FX is sure to rise to the occasion.

Whichever style you choose, you can rest assured that Reebok's Nano series will never steer you wrong, thanks to years of design research. They're not only functional but also incredibly versatile, making them the perfect complement to your entire workout wardrobe. You can effortlessly pair them with a range of bottoms, including high-performance 7/8 leggings, breathable sports tank tops, and your favourite high support sports bra. Mix and match your favourite workout wear pieces to create a wardrobe that's as unique as your goals.

With Reebok's unwavering commitment to quality and performance, you can trust that the Nano series will keep you looking and feeling your best workout after workout.
