Endorphin Speed 5 Running Trainers

Honestly a very solid performing shoe, it’s light, surprisingly stable, and very responsive. Use it mainly for tempo runs but I could daily the shoe.

I use it for workout and races. It works very well for me.

The shoes are incredible! For every type of run, they are doing great! Only one thing: I use to wear 9 with the speed 4 and unfortunatly for the speed 5, I should have ordered 9,5. They are a Little snuggier

Light and versatile. Lots of energy return. A great short and long distance shoe.

I bought this shoe hoping to use it for my faster runs. The shoe felt decent at first but foam already feels worn only a couple of runs in. Was expecting a little better quality for the price.

The Endorphin Speed 3 was great. The 4 was good, but the foam felt a little harder than the 3. With the 5 the sizing is off. It feels like my foot is slipping around in it while I'm running. The next size down was too small. The older versions fit like perfect glove without being too tight. It's a neutral shoe, but the arch support feels off too, and it doesn't encourage "speed." I would not wear it in a race (tried to, in a marathon). Still a decent daily trainer, but just used to feel better, IMO.

I tried really hard to like this running shoe but even after trying three different ways insoles and going on three runs I could not run in them without pain on the outside of my left foot. I went back to my other shoes and there was no pain. Unfortunately Saucony does not have a guarantee or do any type of refunds if they are used so it was a waste of money. I will not be buying or recommending Saucony products unless they change their policy.

My husband has never tried your shoes. I have been a big fan. I bought a few pairs because of the color patterns and he loves them

These quickly became one of my favorites in my weekly running shoe rotation. Plenty of support, fit true to size, and comfortable.

been using endorphin speed for the last 4-5 years and every model is an improved version of the already excellent past model

True to fit. They are pretty responsive, bouncy shoes. The foam reminds me of boost up close. Only have ran a couple miles so far but they’re great so far.

It is a decent shoe overall! That being said, for me, if I compare with speed 2, Saucony is going backwards in so many ways! With every new model from certain series (speed in this particular case), Saucony is pushing the newest technologies to the superior more expensive product (for instance, pro). That is a pattern from Speed 2 onwards. It is a shame, in my opinion, because when comparing, speed 3 was less comfortable than speed 2 and speed 4 is even less comfortable than speed 3. I am not happy with that at all, although the quality of the product is great as expected.

The Endorphin series is the best running shoe I’ve had as an older adult. Great support, with a pillowy soft landing, though light weight. I’m in my 80s, but still do a routine run on a track surface only. This is my second pair, and I will continue to buy them in the future. I hope the series remains consistent over the years to come; they’re great!

I bought this shoe in December of 2025, and have put 110 miles on them up to this review in May 2026. I really enjoy how light and firm this shoe is. It also has enough stack to keep me comfortable on my longer or slower runs. Sadly, the shoe is starting to come apart a bit. It’s a small thing, but it’s right up against my pinky toe which is really annoying. It seems like a design flaw alongside failing glue. I looked into doing a warranty claim but the process is ridiculous. Requiring proof of purchase, making the customer pay for shipping, and keeping the shoes for months just to make a decision about whether they will replace or not. I’ll fix these shoes, but I don’t know if I’ll buy Saucony again for fear of a warranty issue
