I bought these to stop the insufferable chaffing I was getting during my long distance runs. I got them right before I ran the Philadelphia Half Marathon and give them a try then. No chaffing, no discomfort, no sweat build up. I have gone from pain after a run to feeling like I did before I started the run. You won’t regret buying these!!!!
Let's face it. I'm old and no size 6. Or 8. Or 10. Or 12. Let's call me an XL.
I am a cyclist mostly and a walker.
I first found the briefs on amazon. Bought a pair. Loved them Came here to buy some more. I ordered a 3 pack, I think and in the pack were the long running shorts. I thought, "What the heck. I'll try them under a dress". On a 90 degree day with high humidity. I don't do heat. I have not been able to wear a summertime dress for about 20+ years because of Chub Rub and my thighs rubbing together like Velcro. Ugh! .That feeling!!! I tried Spanx and stuff like that but, OMG, so HOT!
Well, lo and behold, after putting on the Running Long Shorts the heavens opened and angelic choirs sang! I wore that summer dress and didn't feel hot, sticky or generally gross.
As a side note, prior to this, I used a cycling chamois butter to help with this problem but, while that DOIES work, it's kind of gooey.
The only downside to these Shorts was the waist occasionally slipped but it wasn't a game changer.
So, in short, I HIGHLY recommend these for under summer clothes, like dresses. .
I bought the three pack about a year ago. I thought I was the only one chafing this badly. It can be rough as you know. These Runderwear boxer shorts fit quite snug. I'm wearing the medium based on the sizing chart. Don't know that I'd want to wear them all day. They are PERFECT for running though. I have other underwear that I wear that aren't quite as snug, but I'm far more likely to chafe, especially with the summer heat. I began running in my early forties, and I've grown to love it. Unfortunately I chafe easily, all over. It's been tough finding the correct clothing, but Runderwear is the underwear for me! I'm on the site to buy more!
I run outdoors all winter long in Minnesota. Needless to say - I need to layer up a LOT! My butt and thighs tend to get super chilly - so I always wear a bike length merino wool short, with a similar 'underwear' short under those. These are EXACTLY what I was looking for! They work perfect under tights for cold weather running. I wasn't sure if they were more of 'shorts' or an underwear base layer. Most reviews talk about wearing them just as shorts. They may be a bit thin for that (see through?). They are so comfortable and breathable. They stay put and don't pinch. Absolutely perfect as an added base layer in the cold winter temps under tights! I'll be ordering MORE!!!!
I have three pairs of these underwear. They are absolutely 100% worth every penny! I’m a runner and have experienced ZERO chafing wearing these underwear. Great product! Highly recommend to those who run long distances. I’m 160 and wear a large. I would recommend washing by hand or in a laundry bag in washer. So comfy! 😁👍🏃🏼♀️
The best sports underwear I’ve tried out of a big range. Great product, super comfortable and comes with fast delivery!
These are really comfortable, even on really long, wet runs when most things do start to rub, my feet remain blister free. Highly recommended.
I was given a pair of Runderwear last year and my initial thought was "what's the big deal, surely underwear is underwear!" I then ran in them. GAMECHANGER!!! It turns out not all underwear is equal after all and I now own over 5 pairs and will not run without them. I tried the running bra this week and although I still need my normal running bra, the extra support it gave me was amazing and I LOVE the material and colours.
I highly recommend Runderwear to all runners. We spend so much money on the gear you can see ie shoes, kit but the clothes that we wear next to our skin we tend to wear anything but wearing Runderwear means you run in comfort, not chaffing and the slogan #dontruncommando makes me feel like a real running ninja :)
These are great, fit beautifully and made with such soft material. Will be buying more
After running for a number of years and trying various anti chafe creams I finally moved to runderwear about 2 weeks ago. Safe to say I love them, it feels like your running without anything on whilst knowing that your run will be completely chafe free. This has come at a time where my training is being ramped up in the run up to my first marathon in October so being able to run distance comfortably is a massive plus for me. I've got up to 13 miles with no issues and am looking forward to running in them during my marathon training.
Another top product from these guys! Always innovating and the quality is first rate! I’ve run half marathon, full marathon, ultra and obstacle events and they’ve never let me down!
Once again Runderwear have produced another top quality garment you can feel the quality as soon as you put them on. I have waited to do quite a few runs in my new briefs before reviewing them and I can definitely say I am not disappointed, lovely snug fit and when you are out on a run it feels like you have nothing on they are that comfortable really glad I brought 3 pairs now as I would highly recommend them to anyone it’s a 10 out of 10 for me 👍
Having been in training since February for my first marathon (in May - Liverpool Rock and Roll Marathon) I had endured a lot of pain with chaffing especially on my long runs. I had tried cheaper chaff free versions but they had failed to stop it! My only long run left... was the actual Marathon! So in desperation and with not a lot to lose - I bought these and the first time I wore them I ran a Marathon in them!! THEY ARE AMAZING!!! No chaffing WHATSOEVER. I will be recommending these to anyone who will listen to me!! Thank you so much Runderwear for a pain free (ish!!) Marathon. xx
The best socks I've ever had. Good fit, with no bumps or pressure points, and a really good amount of compression - plus the added bonus of protecting your legs against undergrowth and thorns. In terms of heat, they've been on 11hr + runs in the height of summer (in Southern France and the UK) and never had an issue with feeling too warm. After a solid year of use, they're now showing wear and holes are appearing. Hope they restock soon!
Size Notes: Small with size 6 feet fit perfectly.
