JOIN NOWThe last few years have seen a huge rise in interest in carbon-fibre running shoes.
Shoes where a stiffer plate is inserted in a well-cushioned midsole to help forward propulsion in the last phase of the gait cycle is not a new idea by any means. Several companies have implemented the idea in various ways over the last 20 years.
The combination of a carbon plate, super springy cushioning and the right “rolling geometry” has spearheaded the current wave of shoes. The increased performance indicators at elite level – notably the sub-2-hour marathon – have engendered much debate amongst runners at all levels. One thing for sure: carbon-plated shoes are not going to go away for the moment.
Simply put, carbon fibre plates are like springs that propel you forward. Basic biomechanics identifies 3 phases to the gait cycle of most runners:
The combination of the rocker-like geometry of the designs, together with the spring-like qualities of the plate, when used in conjunction with a soft springy midsole, just seems to enhance forward motion – and quickly.
In our opinion and experience, shoes with any kind of enhanced forward propulsion like carbon plates are engineered to improve performance.
Although in the last two years performances by elite runners in carbon-plated shoes have broken records and hit the headlines, performance is all relative. Obviously, if you want to improve your running, you have to train and train hard. No pair of shoes by itself is going to help that. Having said all that, whether you are an elite 10km or marathon runner going for a national record or a club or recreational runner just aiming to improve your PB, little things do matter! If you are convinced by the arguments that a carbon plated shoe will help you improve, there is only one way to find out.
Some companies would lead you to believe quite a lot, and the mythical 4% figure has been often quoted. Trying to find independent research not involving a running brand is not easy but does exist.
You, as a runner and we, as a retailer, always try to go beyond the headlines or the tweet or the marketing hype to see, “what is really going on here?' Any coach, in any sport, will tell you it is hard consistent training and attention to your running form &ndash sometimes for a few years – that brings genuine improvements.
However, performances by elite and club runners wearing carbon-plated shoes have shown substantial individual improvements at a range of distances from 5k to 50 miles. Or as people often say, “The stopwatch doesn't lie.”

Mach X 2 is a fast, super-cushioned, propulsive shoe that will take you from quick training runs to racing and your next PB! The very popular Mach X gets quite a big upgrade with V2. There's more cushioning and 5mm increase in stack height, but the weight stays light. The Pebax propulsion plate now sports winglets – basically for stride efficiency.
Saucony's Endorphin range is at the cutting edge of innovation, featuring Speedroll technology. The Pro and Elite have a carbon plate, while the Speed has a plastic/TPU plate. Saucony has a great reputation for this technology and continues to impress. Read on for details of each...
The Elite is top of the range in the Endorphin collection, made for performance and competition. Maximum cushioning is packed into the PWRRUN HG midsole, with 8mm drop.
Stack Height: 40/32mm
Average Weight: Men's 204g
The built-in carbon plate is slotted for increased flexibility, which makes this incredible racer move with the foot. Flexibility is not compromised by the powerful propulsion from the carbon plate – on the contrary, it maintains a smooth, easy ride.
The luxurious PWRRUN HG cushioning offers maximum bouncy comfort and energy-return, alongside impact-absorption on roads. The feather-light upper promotes excellent breathability.
Just by trying on and testing Endorphin Elite one notices the huge point of difference: ultimate step-in comfort and a stable, smooth yet propulsive ride, with a lightweight feeling on your feet.
The Endorphin Pro is designed primarily with performance and competition in mind. It's constructed on what is Saucony’s standard 8mm drop.

Average Weight: Men's 212g
The Speedroll technology has a geometry that – like other shoes in this genre – generates a lively forward roll for a natural and responsive ride.
Saucony's luxurious PWRRUN PB foam cushioning features PeBa technology. For the average runner it is basically very soft and protective but, with the S-curved carbon-fibre plate design, naturally propels you through the gait cycle.
It is a great shoe to rival any of the other carbon-plate editions at the sharp end of any race field.
The Endorphin Speed is the most popular of all the Endorphin racing shoes. It's more agile than the PRO but still delivers powerful propulsion, to help you to achieve our fastest speed.
