Why we made the Endorphin Belt
A Frustrated Runners journey to create the best belt in the world
The founder, an Army Ranger, marathoner, and ultra-marathoner, was frustrated with the existing belts on the market.
Every belt he had tried:
Bounced or Rode Up
Had Limited Storage
Was Too Bulky
Fit Body Awkwardly
He wanted a slim, lightweight, and simple belt that was functional enough to carry his phone, hydration, and nutrition for racing, everyday use, and trail running—without the unnecessary weight and bulk of a vest.
So he created the Endorphin Belt — a sleek, high-performance solution for runners who need gear that keeps up

Just ran 12 miles this weekend with this belt. It was like it wasnt even there. Extremely comfortable, functional, and necessary if you run on regular basis. Great product, awesome company.
Running in south Florida presents some unique problems. One of the obvious ones being hydration. Often for long runs one handheld isn’t enough. But who wants to have two bottles or a vest all the time? Being able to go hands free or carry extra hydration especially on my long runs is a game changer. Great fit. No bounce. This is the solution I’ve been looking for.
Just ran a 5.3mi this morning with it and loved it! The soft flask was easy to use, no sloshing, no leaks whatsoever. Belt stayed put, no bounce.
I love my running vest, but it feels SO heavy especially in the summer and can cause chafing on my shoulders. I was skeptical about this belt, especially as someone who’s tried so many other brands. I LOVE THIS BELT - no idea how but it really doesn’t bounce and because of the thicker straps, it sits very comfortably on my waist AND still has so much room for everything I need from 1 mile to 26+!!!
I appreciated the clean delivery of the sales pitch i received at the Philly love run, pick up place. I used this equipment for the Philly love run and can confirm there was no bounce.
I wish you the best for the future.
