Hoka Carbon X 2

The Hoka One One Carbon X was the first shoe of the brand to feature a carbon plate. One year later, Hoka persists and signs with this resolutely firm model despite some signs of softening.

First of all, we must put the Carbon X 2 in the context of 2020. After the rush for carbon footwear in 2018/2019, the novelty stage has passed. We are now spoilt for choice, with every major brand offering at least one carbon-fiber plate model. In this regard, the weight of the Carbon X 2 is in the high range with 239 g/8.4 oz (men's model). In comparison, the Adidas Adios Pro weighs 224 g/7.9 oz and the Nike Alphafly 229 g/8.0 oz despite their high stack height close to 40 mm.

The Hoka Carbon X 2 offers a thinner sole than before with 32 mm for men and 30 mm for women under the heel with a 5 mm drop. The cushioning of the PROFLY X midsole and its CMEVA foam is softer but remains firm overall. The carbon plate, which was very stiff on the first model, is also a bit more flexible, which gives a smooth but less propulsive ride than before, according to the testers. Also, the softer cushioning reduces the ground feel. Overall, this slight configuration change provides greater comfort and versatility for longer runs.

Next, the upper remains very similar to the first model, but with a new sleek flared heel. It was well-received overall, especially because of its padding that locks-in the heel comfortably in the shoe. Besides, the mesh is a little thicker, which makes it more resistant than before. The result is a tighter lockdown. The testers praised this improvement, noting that it makes the shoe more suitable for racing. Finally, the wide, foam-rich "Swallow Tail" heel adds stability. It's specially designed for runners who heel strike (the majority) and provides more comfortable cushioning upon landing. However, if you forefoot or midfoot strike, the benefit may be minimal, and the bulky piece may even weigh you down for nothing.

When it comes to durability, the rubberized foam of the outsole is frankly not ideal for high-mileage runners. For example, some users have noticed wear signs after about 250 km/155 mi, which is not great considering the shoe's price. Unfortunately, it's often the case with this type of shoe.

In summary, the Hoka Carbon X 2 remains true to the first model with a firm and springy cushioning that lends itself well to long distances. However, the shoe seduces without impressing, and its durability limits its versatility. In other words, it lacks this WOW factor to instantly turn heads. Hoka fans, go for it! For others, take the time to compare with other carbon-fiber plate shoes to determine what suits you best.
