There is no longer any doubt that carbon plated running shoes like the Nike Vaporfly offer tangible performance benefits. However, as good as they are, super shoes have several drawbacks that put off many runners.
For one, they are very expensive, usually over $200/£200. The Nike Alphafly NEXT% 2 is currently the most expensive and costs $275 / £275. Super shoes also don’t tend to last that long, with many going past their best after around 200 miles.
Decathlon’s new carbon shoe has none of these drawbacks. It costs just £129.99 (TBD) and has a 1,000km warranty. It also contains the key ingredients of an authentic super shoe, with a full-length carbon plate and PEBA-based midsole foam.
The performance of the midsole foam will determine if the Kiprun KD900X is a success. Nike’s ZoomX cushioning, used in the Vaporfly and Alphafly, is also PEBA-based, as is the PWRRUN PB foam used in the Saucony Endorphin Pro 3. However, not all PEBA foams are the same and their use is not a guarantee of success.
The KD900X’s midsole is firmer than other PEBA shoes I’ve tested, but I only wore it for an easy 5k run at the UK launch event. I expect it to be softer because it is designed to be such a durable shoe.
As you would expect from a carbon racing shoe, the KD900X has a lightweight upper and fairly minimal outsole coverage, although the impact areas around the forefoot and heel are covered. of rubber. The shoe has an 8mm drop and I found it to be a bit chunky and an EU 43.5 fit better than my usual EU 44. It weighs 7.9 oz / 225 g (EU 42).
The Kiprun KD900X is at the heart of Decathlon’s efforts to establish itself as a performance running shoe brand offering excellent value for money. Other new launches include the Kiprun KS900 padded shoe, which costs £99.99, and the KD800 short distance speed shoe, which has a PEBAX plate and costs £90. The brand has also sponsored elite French athlete Yoanne Kowal, who ran a 62-minute half marathon in the KD900X and will wear it for the London Marathon in October.
We’re excited to start testing the Kiprun KD900X, and while it may not meet the high standards set by the best carbon shoes, it still has the potential to be a great fast training shoe given its durability and of its low price. The firmer ride could also be beneficial for runners who have found super soft shoes too unstable to use. We’ll have our full review of the shoe as soon as possible.
