Team Accelerate athlete and shoe hoarder Harvey has been lucky enough to get his hands on the new Saucony Endorphin Pro 3. He’s been busy testing them, keep reading to hear his thoughts.
I have to preface this review by admitting how much of a fan I am of the Endorphin Pro 1 and 2. For the last few years, they have been my go to road racing shoe from 5k to half marathon. I have run almost all my best races in them, and from the first run to now I get excited and enjoy running in them, a lot.
So when I found out that Saucony we’re updating them, I was a little worried. Well, there was no need.
Version 3 of the Endorphin Pro sees some pretty major changes. First off to the upper. Stripped back to the bare minimum, Saucony have used a perforated mesh to maximise the breathability and stop the shoe from picking up any extra weight if you are running in the rain. Something which happened in the older models. Even the tongue features circular cutouts to reduce the weight.
The next big change is the midsole. Now with an extra 4mm of PWRRUN PB cushioning to look after your legs. They do, however, still use the same S-shaped carbon fibre plate as before. Along with their SPEEDROLL technology to push you up onto your toes for a snappy feel.
Finally, the outsole now uses a new rubber layout. With more coverage across the shoe and deeper tread (1mm lugs) that offer better traction in the wet and hopefully increased durability, I need to run in them more to confirm this.
On foot feel
Slipping them on and straight away they feel light and airy, slightly roomier in the toe box compared to previous models. The new tongue feels comfy even with its cutouts. They feel very secure on my feet even when cornering, which is impressive for such a tall shoe.
While there is now slightly more foam under you they still feel pingy and responsive. Amazingly they have managed to strip weight off too which is always good.
The carbon plate and aggressive Speedroll pushs you onto your forefoot, this is nice and gets you up and moving quickly but takes a little getting used to. If you have had the older models the 3’s have a very similar feel. One of the most noticeable differences is to the outsole, I never thought the older ones slipped much but having tried the 3’s, wow. The new pattern ias much grippier and fills you with confidence, even in the wet.
- The new upper still fits well and feels lighter
- Fast, while this might sound obvious for a racing shoe, they do. Put them on and you want to run quick
- Shaving off 9 grams. While this might not sound like much over the average 55,000 steps of a marathon it can add up
- They are Pink!!! Need I say more
Con’s (There are very few)
- The laces, I’m not a huge fan of. After I switched them over I didn’t have any issue
That’s really it on the cons
I think if you have had an older model and are ready for a new pair you will love what’s been added. If this is your first foray into a carbon plated racing shoe what are you waiting for? The hype around them is real.

Team Accelerate member and On athlete Andy Shelton has been putting the new On Running Cloudboom through its paces.
Heel-toe drop: 9mm
Best use: Road Racing
The CloudBoom is On running’s adventure into the world of carbon infused running shoes, The CloudBoom has been engineered for fast marathons and road races.
Straight out of the box
When you pick up the shoe, you immediately feel how light it is compared to On’s other long-distance, race based CloudFlow and CloudSurfer running shoes.
The CloudBoom is very distinctive. Many design hours and fine-tuned running tech have gone into creating an absolutely gorgeous shoe. As On say – this is definitely “Swiss engineering at its finest”
You will be pleased to know that the CloudBoom retain On’s signature cloud shaped sole. However, it is certainly fair to say that aesthetically they are rather different to On’s regular shoes. It is the only time I have seen a shoe and said “it looks fast”
When you push off for your first run, you appreciate Ons carbon infused speedboard. This flexible, but not pure carbon, speedboard offers a good balance of both rigidity and robustness, so every
step feels light, fast, and responsive.
The materials used in the CloudsBoom tick every box. The upper consists of super quality, ultra-thin and breathable engineered mesh to keep the weight down. The forefoot is reinforced so it can handle all types of turns.
The CloudBoom is well cushioned yet very different mainly due to the exciting set-up of the sole. Side on you can clearly see the different structural layers. In between the top section of the sole, (which incorporates On’s Helion™ foam to aid comfort), and On’s fabled CloudTech™, sits the carbon infused speedboard.
The rubber sole is noticeably different from On’s normal road shoe models. This is to offer you, the runner, enhanced traction and grip in the wet – which could provide increased acceleration and confidence. On have also made some other tiny changes such as the shorter tongue, which minimises weight and shows how On are trying to maximise the efficiency of this shoe.
Compared to the other carbon shoes on the market, the On CloudBoom is considerably more subtle, definitely not shouting out to everyone that you are out to PB, more like running in stealth mode.
After 3 weeks of testing (70 miles)
the new On CloudBoom I have noticed a few things; they are comfortable and super smooth to run in, the shoe is really snappy and provides a quick return for maximum cadence, and definitely has been easier on my legs, calves and achilles, which, for long distance runners, is a must. These shoes basically worked with my body and responded to the amount of effort I put into them. I tried them over a long distance, intervals and mixed pace runs. They responded superbly and I got the extra kick when I needed it. They are definitely now my favorite On running shoe, and most certainly a game changer!
Shoe looks good
They seem to be a bit unstable in lateral motion
Pick up stones
Not for the weekend warrior ( casual runner )
Small toe box
the CloudBoom is best suited to the road running for a decent amount of training miles. A superfast, comfy shoe to take on road races from 5km to Marathon distance and to get your desired PB’s.
Fantastic new On running shoe added to the On shoe family.
*I have put the cost in both categories as a carbon infused shoe it’s relatively cheap compared to others, but for the casual runner, it’s expensive and may not be for them.
I have been lucky enough to get my hand on a pair of the Endorphin Pro’s. The latest entry from Saucony in the carbon shoe battle happening right now. If you head to any busy running area you are bound to see at least a couple of people wearing carbon plated shoes.
Ever since the first few companies released carbon plated shoes and amassed a cult following, PB’s and world records started dropping like flies. Until now I haven’t had a pair, so when the Endorphins bounced through the door I was very interested to see if the hype they had built up was really worth it.
The first thing that hit me out the box was “WOW, these are a flippin good looking shoe”. Bright and bold colors just catching your eye. Yet still maintaining the same look of current running shoes unlike some of the carbon shoes out there.
Slipping your foot into them, they are comfy but not plush. They use Saucony’s FormFit to wrap around and hold your foot firmly in place. The upper is lightweight with no added extras to
maintain a racey feel. Its made with a single-layer engineered mesh upper which is highly breathable to keep your foot cool and drain any water or sweat with ease.
The midsole is Saucony’s latest and greatest PWRRUNPB foam a peba based foam. It claims to be super responsive and cushioned but with the longevity of a standard midsole (500 miles). Sandwiched in between is an S-shaped carbon fiber plate, there to fire you forward with every step. Couple this with Saucony’s new Speedroll meta-rocker and it has the potential to be a very fast shoe. It comes in a whopping 35.5mm stack height in the heel and 27.5 in the forefoot for an 8mm drop. Not quite your traditional racing flat.
To finish it off the outsole use a minimal amount of high carbon rubber compound and exposed midsole to keep them down to a featherweight 213g (UK size 9)
Just jogging up and down in them is a very odd sensation. They feel very soft however, you can feel the plate sandwiched in them as if you are running through mud then hit firm ground. Then roll onto the toe and snap forward. Very strange. But not bad at the same time just very different from anything I have used before.
The first proper opportunity I got to use them was a 3k time trial with some of Team Accelerate. I was excited, to say the least, after hearing all the stats that have been thrown about the Endorphin and other shoes like it. Were they really 4% more efficient than a standard trainer? Well…….
They are bouncy, very bouncy. The combination of soft and springy foam along with the carbon plate results in a shoe with a lot of pop. They feel fast, one of the biggest changes I noticed was how much longer I felt like I was in the air after each stride, almost floating. Now I know they are meant to be a marathon shoe but after 3k my legs felt as if they hadn’t done much not sore or tight even when coming down the small hill in the course it didn’t feel as if they were pounding my legs, still just bouncing along.
I know this was only 3k but still for longer races they certainly could come I handy to keep you feeling fresher even in the later stages of a race.
In short, if you can get hold of a pair then 100% go for it, they are an amazing shoe. They make you feel fast and want to run faster! For anything from 10k and above they are an incredible shoe. The one you pull out on race day when you want to rip it and break PB’s. Get a pair here >> today, alternatively take a look at the Endorphin Speed, a more forgiving racer/ quick trainer, here >>
