On the first run in these I was aware of 'sensations'...nothing bad, but I expected to be completely unaware of them, I got that from my £5 Decathlon ones. Well, I think that was just me adapting because I have been not thought about them since. They are super comfy and soft while being supportive as they need to be and don't get sodden from sweat. I got longs for a bit of extra leg comfort but they're not that long and there is no element of compression (and none is advertised), but there is extra warmth which is good in Autumn shorts-but-chilly weather. Zero chafe which is all you can really ask, but I did get that from the cheaper ones and these are four times more expensive...I think they're worth it for being very well made and crucially I have confidence they'd remain that way for longer runs, the furthest I've been in these is 15km and they were great, I could imagine the others getting less comfy over long distance as they're thicker and the seams may have an impact they don't have under 10k. Didn't mean to write an essay- I wholly recommend Runderwear, I think if you only run shorter distances you could get away with cheaper, but these still look like new so I suspect you'd get your money's worth in durability anyway, buy cheap buy twice etc. BTW the blue is more pale than navy, I like it.

Thank you for your feedback this is greatly appreciated. We are pleased to hear that you took the plunge and decided to try out the Long Boxers and you have been chafe free since trying! We hope that you have many happy miles in your Runderwear Underwear!

Thank you for your purchase with Runderwear!

Slick winner

I wish I had discovered runderwear sooner! They really stop you being a sore loser and turn you in to a slick winner! Way above my expectations, highly recommended.The fit is amazing and feel great over long distances. Within a week I had ordered another pair! Awesome 👏

Size matters, pun intended

I thought it would not make a difference if I will take a bigger size, since it's already compressing and fitting the body, but boy was I wrong. The M I bought this time feels much more fitted.
The L is good, but the M is really my size. Amazing fit, very comfortable running, dries up very fast. and it's super light.

Thank you for your feedback, Great to hear that you have now found the perfect fit in your Boxers. We love to hear this. We hope you continue to love your Runderwear garments.
