If you’re wanting to run fast, then you have probably heard of the carbon plate technology that has taken over running. First introduced by Nike and used to set records all over racing. And today we’ll be looking at two pairs of road running shoes featuring the carbon plate technology, the Hoka Rocket X vs Carbon X.
One is the brand’s no frills, light, and fast performance racers. While the other is their introduction to the carbon plate technology and the bases for both of the model builds. These shoes have a lot in common but there are some key differences that may make one the better fit for you. Below is a breakdown of the key differences, specs, photos, breakdown and more!
Hoka Rocket X vs Carbon X
- The Hoka Rocket X is a unisex shoe. While the Carbon X comes in both men and women’s models.
- Both the Hoka Rocket X and Carbon X feature the same “carbon plate” for performance. Carbon plate technology has been proven to increase rebound speed.
- The Hoka Carbon X are light, but still slightly heavier. The Rocket X are incredibly light. With all the extras cut to save weight.

Performance Summary
When comparing the Hoka Rocket X vs Carbon X the first thing we need to do is understand how the carbon plate technology works. The carbon plate is in the shape of an >, so that when you step down the carbon plate, it compresses and then springs up propelling your foot forward. This technology has been tested and proven to increase performance and is banned in some races.
Hoka is one of the newest and fastest growing running shoe brands on the market. And one of things about the brand is that they aren’t afraid to push the limits and test out new technologies. So not only did Hoka create a shoe with this carbon plate tech, they created two! So let’s break them down below.
Hoka Rocket X
Based on the Carbon X, Hoka’s first carbon plate shoe, the Rocket X is a stripped down road running shoe. Designed specifically for race day and running anywhere from 5k to a full marathon. But how do they feel and perform for a mere mortal like me?
When I first put on the Rocket X I couldn’t help but notice how narrow they are. Definitely plan on going a half size up even if you don’t consider your feet wide. I think part of this is due to this being an “unsix” shoe. Something that is very hard to pull off. And a lot of the women’s reviews say that the Rocket X is very much a men’s shoe.
The overall build quality of the shoe feels very light and breathable. But a bit flimsy at the same time. And to me the shoe feels a bit unrefined for the high end price point. Part of me feels like the lack of women’s line and overall build quality are signs of a shoe rushed to market.
Running in the Rocket X, they are lightweight and breathable. And the carbon plate rebound provides a very quick and springy turnover. They feel fast. And with the 5mm drop they were great for my 7-10 mile runs. The one issue I ran into was that in the streets in the winter, they are slick. I wish they had more traction and a bit more cushion. But for a shoe designed for racing. They wanted to cut every bit of weight possible.
Hoka Carbon X
The Hoka Carbon X was the first brand’s first model to feature the new carbon plate technology and has been the base that the Rocket X has been built off. Designed to compete with the Nike Vaporfly, the Carbox X would fall into Hoka’s racing shoe line. Really targeting higher end runners. And that’s apparent when you first try them on.
Compared to other Hoka shoes, the Carbon X feels a bit stiff. And you don’t really get the full feel of the plate until you get running. And even then you notice it more once you get a chance to break them in. Fit wise the Carbon X runs a little big. Probably about a half size, but this is common in a few other Hoka models. They are incredibly light. But do feel a bit flimsy in the fabric on top. I understand this though, trying to cut every bit of weight they can.
Performance wise, these things are fast. I enjoy the fact that Hoka kept the 5mm drop and still managed to make a shoe that feels like it wants to go. This is not the case with some of their heavier, more padded shoes. The carbon plate is really noticeable at speed and when pushing. And they just feel fast on your turnover.
For me the biggest downside of the Carbon X is the overall durability for day to day use. The soles don’t have a ton of traction and I’d be worried about wearing these on wet days. And I’m just not sure they are going to get me 300+ miles for an upper end price tag. But if I can afford the luxury of buying a shoe specifically for racing. Then these would be a contender on my list.

Conclusion – Hoka Rocket X vs Carbon X
Hoka has extended its carbon lineup providing runners a few options to choose from. Using the Carbon X as a base, the Rocket X is leaned down unisex racer. But when looking at the Hoka Rocket X vs Carbon X there are some big differences. Especially in the sizing, overall build feel, and durability. While the Rocket X is narrow with less padding to cut weight. The Carbon X is wide with a little more padding and a slightly sturdier build quality. They both offer incredible rebound and turnover. And carbon plate technology is definitely here to stay.
So which one is right for you?
Which road running shoe to buy?
After running both of these shoes, for me there is a clear winner. For me I liked the fact that Carbon X was a bit more roomy, has a little more cushion, and comes in both men and women’s sizing for better fitting. The build quality feels a bit better and I feel like you will get more miles out of them. And did I mention they feel fast! So for my money I’m going with the Carbon X. And can see these being my go to road racers.
I disagree with your assessment. I did “extensive” research and all reviews point to the Rocket X being the “race day” shoe? Why, because it s a full oz lighter in weight than the Carbon X. The Carbon X is NOT a racing shoe. Maybe a daily trainer but that’s it.
