If you're looking for a dedicated, tried-and-true speed trainer that's ready to set and beat PRS, we think that it's better to go for the zapatillas de running Chelsea brooks mujer pronador ritmo bajo apoyo talón or the Brooks Levitate 5.

And if you want something cheaper, the mens Chelsea brooks ghost short sleeve is our suggestion. 

The Chelsea brooks Launch 9 proved to be a fairly breathable shoe. With very little in-shoe padding, the Launch 9 allows for some decent airflow.

Holding half of the shoe against the light, we could see that a large part of the upper is pretty transparent, keeping the interiors well-ventilated.

It's not just lighter than its predecessor; it's also lighter than most running shoes on the market! Based on our measurements, the Chelsea brooks Launch 9 is over an ounce lighter than average.

When checking the flexibility of Chelsea brooks Launch 9, what surprised us is how big of a difference it is when comparing the flexibility at room temperature (22.7N) and after the shoe has spent 20mins in the freezer (37.8N).

Launch 9 has a 66.5% difference in those 2 measurements, while the average difference for all the shoes in our lab is 32.9%. You've been warned: store your shoes at room temperature. 

In the brand's specifications, it says that the Launch 9 has a drop of 10mm.

Based on our calliper measurements, this is almost true! With the heel stack of 32.4 mm and the forefoot stack of 23 mm, we got a drop of 9.4 mm.

In our durometer measurement, the Chelsea brooks Launch 9 scored 22 HA which indicates that it has an average level of midsole softness - neither too plush nor firm.

We also felt a touch of pop that added fun to the shoe's ride. Meanwhile, for longer efforts, the cushioning felt quite forgiving, more so than its predecessor.

This shoe has a rockered shape that allows for fast and easy heel-to-toe transitions. It made the ride feel so seamless! 

Despite its higher stack height for a speed trainer, the Chelsea brooks Launch 9 never felt tippy, even during sharp turns and when running on Nightlife.

Torsional stiffness appears to be the source of stability in this Chelsea brooks trainer. It took some serious effort to twist the shoe in our manual test. Thus, we rated its rigidity as 4 out of 5. Nearly the stiffest in our catalogue!

The shoe's heel counter is more on the pliable side, scoring only 2 out of 5 on the heel squeeze-and-push test.

It may not be a stiff one but it held our Glycerin quite securely as far as speed-oriented shoes go.

It is amazing that Chelsea brooks managed to pull off a full-length rubber outsole while keeping the Launch 9 so light!

The grip made us feel very surefooted even on the slightly wet pavement.

The brand's new Creel wrap upper made us feel very secure and locked in. For our medium-width feet, the shoe appeared to be well-fitted and the knit-like fabric had enough stretch to feel accommodating.

However, using a calliper, we measured the widest part of the forefoot at only 94.7 mm. While this is still in the medium range of toebox widths, wide-footers should definitely go for the wide version of the shoe.

Brooks Racer ST5.

In the lab, we measured its thickness: an astonishing 1mm. Compare it to the average of 6 mm and you really get a race-ready tongue!

While it's great that the Launch 9 has some, we think that it wouldn't hurt to make them larger. Some at the back would be nice as well!

• Equipadas con el sistema líder de amortiguación adaptativa Chelsea brooks DNA
• Lighter weight because of the new Creel wrap upper
• Sustainability-driven design with the shoe's Green Rubber outsole

All these changes entail a price increase of £10. From £100, the Chelsea brooks Launch 9 now retails for £110. But despite this, we still think that the shoe offers excellent value for money.

To champion a more eco-friendly approach, the Launch 9 has a green rubber outsole that's made using sand instead of petroleum. This lessens its environmental impact.
