They are simply fantastic

These are the best running shoes I’ve ever tried. The special technology provides a great push and saves energy. They are so soft that it feels like you’re running on clouds. This is my second pair that I bought to have as a backup because they are just fantastic. Thank you, Saucony, for such a wonderful design👏👏👏

painful and they squeak!

After loving the Endorphin Speed 3, I purchased these hoping for similar results. Unfortunately, I had many problems with these. The soles of the shoes squeak horribly, on any surface. As others have experienced, my toes also go numb in these. I loosen the laces to prevent this, but then the shoe lacks support. after about three weeks of suffering in these, I started to get horrible back pain. These shoes are overall uncomfortable, squeaky, and feel like plastic. I am very disappointed in the Endorphin 4 compared to the 3.

Sizing Inconsistent

My normal shoe size is 6.5, running shoe is 7. I tried this on in purple, 7.5 too small so they brought out an 8?? To try in black. It was 2 inches too big. The last saucony shoes I bought were

I purchase the shoes about a month ago. I really like the cushion and the design of the shoe. The shoe design allows me too run on the ball of my feet. The shoe is light and the cushion is not overwhelming.

Extremely disappointed
Originally posted on Saucony

I bought this a few weeks ago to add to my line up. Did few runs and was fine, but at the same time felt like toe box was a bit smaller. Went to run half marathon and it was an absolute nightmare. My foot was so cramped up and numb that I actually had to take the sole out and continue my run to the finish line. I do not have wide feet. I can't return them, so literally threw it in the garbage bin. Extremely disappointed. Will be looking for a new brand perhaps.

I got this shoes for Hyrox. What’s. Great running shoe I will say that is difficult to do the sled push. Heel comes out but excellent for all other stations

Perfect for tempo and interval runs!

Perfect shoe. I got these for tempo runs for my last marathon training block and loved every run in them. They are super light and you can really feel the rolling sensation the nylon plate provides. My current pair has a little bit of life left in them, but I will be buying another pair. I'd recommend a half size up for comfort.

Not endorphin speed 2
Originally posted on Saucony
Bought these in hopes they would be as good as the endorphin speed 2 or better. Unfortunately not even close so returned them. The only thing better is the color schemes, finally! But now it doesn’t matter because the shoe is different. Looked on the Internet for hours to find my size in the 2’s. Found two pair. Now I will have two pair of ugly shoes that I love 🤷🏻♀️

They are one of the best running shoes I have ever bought. Shin splints are a thing of the past. When running in the rain they can be a little slick other than that amazing product would buy from this company again

Love, but too narrow!

I bought this a week ago in a half size larger than I wear for a normal shoe, which is my typical running shoe size in all Saucony and my toes were pinched! I wish they came in wide widths because I love the shoe!

Almost A Happy Camper
Originally posted on Saucony

This pair of running shoes were a pleasant surprise. Extremely light weight with perfect cution, it feels likes your running on clouds. The material use on the upper is strechy with breathability that I haven't had sweat problems. But there a few issues that came up with these running shoes. I have wide feet, after running for a couple of miles it starts becoming a problem of comfortability, I wish they offered a wide option. Also, the shoe laces are a bit small since I have wide feet. Thanks for the technology.

Lightweight with tons of support
Originally posted on Saucony

This was my second purchase of the Speed 4. The toe box is perfect for my foot imperfections. It’s lightweight, however I feel ankle support especially on turns. I love the little bounce of the midsole. If there was one tiny area of opportunity, I would share that this may not be your “long run shoe”. Overall, solid shoe for any surface and short to mid distance.

Incredible

Absolutely love these shoes. I was a massive fan of the Speed 2s and went through a few pairs and was really disappointed when the 3s came out - they felt too sloppy in the upper and didn’t feel as responsive when running. The 4s remind me of the 2s but provide a lot more stability. On my second pair now. Use them for my long runs when I want to get a bit more out of myself and not have my legs feel as destroyed the next day and for speed work - great for both!

These shoes are a treat to wear. They’re highly responsive, springy, and just fun. I’m curious how the outsole durability will hold up, but so far so good!

Very comfy, great kick
Originally posted on Saucony

Love these - was looking for a marathon training shoe for both speed work and easy runs. These are comfy and provide a good kick too. I sized up 1.5 sizes because the toe box tapers quite a bit and I’ve had no issues with black toenails (a major challenge for me - I’ve tried many different shoes!). Really love these shoes! Have them as part of my regular rotation but could also see myself buying a second pair to save as my race shoe.
