Endorphin Speed 4 Sports Trainers

First pair was fantastic and snappy. Second pair was completely different- too flexible and soft.

Extremely comfortable. Excellent for daily training

Not at all like the 3's, I didn't feel much bounce or cushion and the outside of the ball of my feet went numb while trying them out. Had to send them back, hopefully the 5's will be more like the 3's

I’ve had nothing but issues with this shoe! Worst edition of the speeds. Dumping it before it causes more damage.

I bought these to train for and run HYROX in and I absolutely LOVE these shoes. They are extremely light, comfortable, and perfect for training all sorts of functional exercises with running in between as well as running in general. These changed my running game, look super cool on the feet, and are my favorite running shoes I've ever owned. I will be buying more colors. Obsessed and highly recommend if you are running or hybrid training.

These are my third pair of endorphins but these absolutely kill my feet. I tried so hard to get comfortable in them but they are so narrow on my feet.

I bought this in my regular shoe size and my three smallest toes got black blisters on the tips. I went up a half size and this still happened. I have loved this shoe and its pro counterpart since 2020. The toe box of this version is just the wrong shape.

I bought the shoes and had less than 30Mils and the rubber came off from the shoes!! not recommend to anyone.

Awful Awful - I have been a dedicated Endorphin runner for years and have purchased previous models in many different colors and have loved every single pair Now the endorphin 4s?? Rock hard sole, No give, Narrow toe box and overall, a terrible running shoe. I have completely switched brands and will not be repurchasing these. I have run one 10k in these and the sole is already falling off they are currently in the warranty process. For the price you pay I would suggest looking elsewhere.

This shoe COULD be great, it’s plush and cushy with responsive roll. I have a narrow foot. But my normal running shoe size 7 was too narrow on my toes and the 7.5 was huge. I previously reviewed this shoe after trying it in other colors and the different colors DO NOT fit the same at all. In the black with blue color a size 8 was too small on me, which is insanity—my regular shoe size is 6.5. ?? When sizing is inconsistent, this is a quality control issue and also makes it nearly impossible to confidently shop online. Side note, the colors are UGLY. Do better, Saucony.

I run 70-80 miles per week for years and only run in the endorphin speeds. I loved the 2 and 3 and have many pairs of those, however I’m so disappointed in the 4s- I don’t feel the speed roll technology, there is minimal bounce, and return of energy. They feel completely different than the other 2 versions. I ran in them once and unfortunately will not be using again. Please bring back the older versions or I’ll have to find a new shoe :(

I ran my first marathon in these shoes this weekend (Los Angeles!) and think they are my holy grail. They are the only running shoes I’ve tried that haven’t given me a single blister. They fit my narrow feet like a glove and I will be wearing these for all my distance runs and races from now on. They are super lightweight and make me feel fast!

I have worn Saucony Endorphin styles for several years and these are the first ones I have been disappointed in. The narrowing at the top and less toe room has resulted in calluses on my toe. The arch is also different. I love the colors but agree with everyone on the toe room and negative effects. Sad because it is an expensive shoe and now I’ll have to purchase a different style.

I’ve been running in this shoe for about a month and I am a big fan. Feels like the perfect combination of bounce, cushion and fit. I have a slightly narrow foot and Saucony has been my go-to brand for 15+ years. They always fit like a glove.
