Saucony  x REI Co-op Endorphin Speed 5 Road-Running Shoes - Men's

Have been a fan of the Saucony endorphin speed line ever since they released. While the four iterations so far have had some highs and lows, the endorphin speed 5 brings a super refined version. In particular, love the new upper and the PWRRUN PB foam is always fun to run in. Also appreciate them releasing these in a variety of colors for everyone's preference! This shoe is a true jack of all trades. Great for just about anything from your daily miles up to some of the faster stuff (and even race day if you prefer). It's a shoe I reach for whenever I'm not sure what I want to run in because it's so dang reliable. I think it shines most though at some speed work (especially tempo-style sessions), but honestly think it can be someone's everyday shoe. Either way, love this shoe. I do hope the next few iterations Saucony will introduce some of the race day foam from the endorphin elite 2s into the speeds. That'd definitely take it to the next level!

Picked up the Speed 5s for uptempo work and long runs while training for the Chicago marathon. Overall, really like the feel, which is light and responsive with lower stack height than a lot of other similar shoes in this category. Fit wraps the foot well with a light upper which feels breathable. Good pickup for the rotation.

These shoes are awesome. They're lightweight enough to be a solid tempo shoe, but durable enough to stand up to more serious mileage. They look slick and the colorways aren't too shabby as well. Highly recommend, one of the best shoes on the market especially at this price point!

Light, comfortable, responsive. Very happy with this shoe.

I bought these Saucony endorphin speed 5 on 7/14/25 from a local sports store and the bottom 'skin' is wearing off already on 8/3/25. So disappointed in the quality or rather lack of quality of these running shoes. I typically run 30+ miles a week so I'm not doing tons of miles and I run road not trail. I was having some issue with my Saucony Endorphin Speed 4 as well and figured upgrade would be better. Although I love the bounce and energy of this model, I'm swearing off Saucony Endorphin Speed for GOOD. These are too expensive for this to happen and so soon after purchase!!

I have been a long time fan of the Endorphin Speeds and was excited to put the 5's on! They are a lot more like the 3's than the 4's are. I can't wait to get more miles on these as I prep for both NYC marathon and Chicago Marathon.

I have been wearing Endorphin for the past two years and was very unimpressed with Speed 5 since they weren’t as comfortable and bouncy as Speed 4. I got a severe shin splint after my first run and unfortunately had to return them.

I really liked the Speed 2, 3 and 4. They were flexible and felt fast. I could slip them on and they fit my feet well. The 5 is certainly different. It's a good shoe but feels stiff and ridged. The 2, 3 and 4 felt lite. This feels clunky, heavier. It doesn't fit my foot as well as the previous shoes and it's certainly more difficult to get through the gait cycle. I can't say I really notice any benefits with the change in the nylon plate. It's not a bad shoe; if you like it, enjoy it. Speaking for myself, I'll have to find something else.

My baseline for this review is the Speed 4. After 80 miles, the ES5 feels firmer, which I don't mind. However, it seems to have lost some of the 'pop' I enjoyed in the previous version. While I can still get a good leg turnover, I just feels a little sluggish. This isn't a dealbreaker; it's still a very solid shoe, though it feels slightly less like an all-around trainer. The upper is 100% improved, and I find the toe box fits better. For me the dream shoe would be the new upper on the old midsole.
