Endorphin Speed 5 Trainers

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

Less than 30 miles with a lot of peeling. Great stability just falls apart.

I bought these shoes seven months ago. I use them sparingly not more than 15 miles a week. The shoes have already started to break down and tear. Wouldn’t recommend them. Disappointed in the quality.

Good cushion but the tongue is so short that you can't even tie the shoe without it sliding down and bunching up.

Looks good. Fits well. Great for performance runs (fast intervals, threshold speed, race speed etc.)

Bought these a couple weeks ago as a first pair of plated shoes for speed workouts. Have done 2 workouts and a long run in them. Feel nice and snappy and carried me to a HM PR. Felt bouncy especially on tired legs. Slight hotspot at top lace on inside of foot but a little working got it sorted out.

This is my 2nd pair of Endorphin Speed 5's and I freaking love them. They are comfortable, bouncy, and the nylon plate is great for daily training. The Shocks colour is darn awesome too!

From the first run I knew this is special, perfect fit and constantly hitting new PRs in my runs since I got it

Love these shoes, I use them for my short and longs runs. Definitely give me what I need to go fast and perfect amount of cushioning for when I’m slow.
