Fit smaller than other saucony shoes. I should have gone up half a size. They are beautiful shoes though. I am bummed I can’t really wear them with them being tight.

I absolutely love these running shoes! They are extremely comfortable, lightweight, and provide great support. They fit perfectly and feel great even after wearing them for a long time. I’m very happy with the quality and would definitely recommend them to anyone looking for a comfortable, reliable pair of running shoes.

Ouch! Can’t Use These For Marathon

I wish I listened to the other reviews. The shoes are going to cut up your ankles. Did a few tempo runs in them, all under 8 miles and definitely felt a little bit of friction by the ankles, but it didn’t break the skin. Then I wore them for a half that I’m using to prep for my marathon and both of my ankles were bleeding by the end. Moleskin didn’t prevent it. Really, really disappointed to have spent all of this money on these shoes only to have to abandon them. There’s no way I’m gonna use these for my marathon. I love all of the other shoes in the endorphin line so this was a big let down.

Wanted To Like These

Been running the endorphin pro for a while. First run in these and I got MASSIVE blisters on both heels. I don't know what's going on with Saucony's sizing but it's all over the place. I ran Boston in the Kinvara and got blisters because the toe box was too narrow. These are too wide all around and I have horrible blisters again.

Not This One

I love the Endorphin Pro 4 and was super excited to try the 5. I only lasted trying the shoe on. I could immediately tell the back was going to rub blisters. I then compared the 4 and 5's and the 5 is MUCH firmer with less cushion around the heel. I immediately returned. So disappointing.

Great Running Shoe!

I bought this shoe for my next race and am so happy I did. Not only is it beautiful, but the support and shape of the shoe also allow my foot to move exactly how I need it to for a comfortable run.

Two Problems: Tongue And Heel

Love this shoe with the exception of two significant wearability issues -- Saucony please fix these as they've never been an issue in previous versions of this (otherwise awesome) shoe! 1. The tongue -- it is a mesh, sewn-in tongue that is too wide, which means it bunches up/folds over itself under the laces and creates uncomfortable pressure points on the top of your foot. 2. The back heel -- it's too high and causes painful rubbing unless you wear really thick socks that come up above your ankle.

Great Training Shoe

I love the shoe for daily training but I prefer the Elite for racing. Overall comfortable and cute colorways.

Terrible Tongue

I’ve worn the Endorphin Pro for the past 3 years and love the lightweight yet cushy feel. But the latest version has a tongue that is unmanageable. It’s so large that it folds onto itself creating rub points under the laces, but worse it is so long that it rubs above my sock line and creates raw points at the top of my ankle. What a waste!

Higher Back Of Shoe/blistering

I echo the negative comments about the blisters on my heel. The back of the shoe is higher on my heel than the 4.0 and starts chafing after a mile. Changing socks/adding bandages really doesn't help. The rest of the shoe seems fine, but this is an absolute deal breaker as this is my preferred shoe for longer races. Love the 4.0, but the rubbing on my heel on this version is a large step in the wrong direction.

Love These Shoes

I bought the shoes about 2 weeks ago and I love running in them. They are cushioned which helps with shock absorption and yet very light. The carbon plate really helps with running faster.

Painful Heel

The spot over the heel is incredibly irritating and painful, no change after a month Pros: great stiff forefoot, lightweight, love the stretch of the top fabric of the shoe.

Not For Me

I returned this shoe. It was difficult to get them on, very tight. And the curved sole felt very de-stabilizing. Did not like the 'rocking' sensation

Not The 4/disappointed

Blister galore even with a variey of socks that cover the ankle and not as springy as the Endorphin Pro 4. Unfortunately, a let down, and will be returning these. Perhaps have runners test these when making them! Bring back the 4.

Light And Good Grip

These shoes are very light and comfortable. They also have good grip for sled push and great for fast transition on HIIT / functional training . It makes running so comfortable. So pleased and highly recommend.
