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 :)

I don’t usually use a belt but I have grown tired of carrying a bottle in my hand. I was impressed that I could adjust it while running. So far so good. The bottle works well but could use a wider opening . I think it will be great for xc skiing.

Great Product ! Highly redcommended ! Stays put and actually does seem like it disappears during training.

This is a really great running belt. I have tried several other brands, and this one is a clear winner. There is virtually no bounce even with the belt fully loaded, which is the thing most belts get wrong. It's extremely adjustable and comfortable to wear, there's plenty of storage space, and the waterproof phone pocket is excellent.
A couple pieces of constructive feedback for the team. First, I wish there were gel loops on both sides of the front pocket so you could carry four gels within easy reach. Second, the front pocket zipper being directly in the center makes it a bit tricky to get a phone in and out — I'm not sure whether moving the zipper to the top or closer to the top would fix it, but it seemed worth mentioning.
Overall, minor notes on an otherwise excellent product. Highly recommend.
