Bought an Endorphin Belt before my marathon last weekend and honestly it exceeded expectations. I had been using a running vest for most of my training, but after switching to this belt I haven’t gone back for my normal runs.

The setup is simple but really well thought out. Phone pocket in the front, bottle in the back, no bouncing, no weird shifting, and it feels super secure even over long distances. The quality stood out immediately too. It feels durable enough for everything from daily training miles to full marathon use.

One of the coolest parts was meeting the owners at the expo before the race. Super kind people, genuinely passionate about running, and then the next day I saw them out on the course cheering runners on. That kind of thing sticks with you.

I seriously hope these guys blow up because the product deserves it. It solved the exact problem I wanted solved without overcomplicating things.

Only suggestion I’d throw out there would be offering multiple bottle size options if they don’t already. I could see different runners wanting different capacities depending on distance or heat.

For me though, this thing has been fantastic. I’ll probably still use a vest for really long unsupported trail runs, but for the majority of my runs, this belt is now my go-to.

I don’t really think it can get better than this! I use to run with the Flipbelt and I was miserable during my half marathon when I loaded all my stuff into it, it not only felt on the bulkier side, but it would not stay on my hips, it kept sliding down.
The endorphin belt even when filled up, feels light and it doesn’t budge! PERFECT! If you are on the fence, try it, you won’t be disappointed, in fact, you will be pleasantly surprised.
Please make in different colors :)

This belt makes use of all available space. I had a previous belt that bounced like crazy and could only hold either my Iphone or collapsible water bottle. I have an iPhone 15 pro max and this belt fits that, the endorphin collapsible water bottle, key fob, and gels. It is perfect on all my runs (easy/tempo/long). I tighten it during faster runs and it does not get in the way. Another huge plus this belt has compared to my previous one is it’s waterproof front pocket for key fob and smart phone. Also their water bottle is the best collapsible one I have found. No weird plastic taste.

Enjoy this belt so far. I've competed in a very tough hill course with it. No bounce and everything stayed in place.

I’m thinner and I have it adjusted to its smallest size. It has minimal to no bounce depending on how many ounces I’m carrying.
