Brilliant top quality product, wished i has purchased them earlier, good fitting, comfortable well worth it, wouldn't buy anything else from now on!
Should of bought these years ago. The confidence from the comfort of not worrying about chaffing is second to none.
Great service and great price. Very comfortable, was surprised at just how good they fit.
Half marathon distance covered with no issues.
Great fit and really quickly delivered will definAtely be reccomending
Brilliant price and really comfortable looking forward to wearing these on many ultra races this year
Excellent service, order came within couple of days
Products I bought are great, do the job they're meant to
Only thing was that I presumed when they said seamless there wouldn't be any at all.....boxers have a seam running right across the front crouch area where I didn't want there to be one :-(
Overall still a great product so would defo buy again ;-)
Bought for my husband. Has some that were purchased couple yrs ago
These new ones are even more comfortable than previous. Very pleased with them. Highly reccomend
I was sceptical before making a purchase, but have to admit so far so good and they feel great compared to other options I’ve tried. Highly recommend runderwear ♂️
Very comfortable. I don't do much running, but these are perfect for walking and cycling. They are very comfortable in the hot weather. I originally bought the long leg boxers for cycling, but the normal leg ones are just as good. I would, and have, recommended these to my friends.
Have only used them a couple of times but they seem pretty good. I agree with some of the other comments in the reviews about the waistband and leg grippers but those aren't show stoppers. The service was great as well. Will likely be getting more of the boxer shorts.
Was struggling with the inner brief of my shorts causing a lot of chafing while on training runs. Decided to buy the boxer short style , cut out the inner brief of the shorts and wear the boxers instead. What a difference! Even though the soreness hasn't fully healed, I did 15 miles with no issues! The waist band rolling up does happen but I don't find it a problem. All in all I think they're great and would highly recommend giving them a try.
I previously ran wearing an Under Armour short base layer beneath 5" shorts.
In this fabulous heat this was proving to hot to continue to be comfortable so I started researching running briefs.
I quickly found this website with lots of positive reviews and reasonable pricing so I thought I'd give these boxer shorts a try.
They are extremely comfortable. Soon after putting them on I forget I'm wearing them beneath shorts. Even in this fabulous summer heat they don't hold heat.
Whilst not used extensively to date, everything about the product and service seem very positive to me so far.
The product is light, comfortable and cosy enough; but noticeably less sweaty than traditional options, even in this hot weather. Size might be on the smaller end of average so if i doubt go for the larger. They are nice and flexy too though.
Good work Rundawear, i'm off to buy another pair.
Really good fit and stops chafing. Now able to run with ease!
Good fit, comfy for long hikes and minimal sweat on hot days.
Arrived within a few days, needed to swap the size over so got one refunded then reordered the size up. All complete with a few days. Great service, great product.
I read the reviews, & they are true!
Fantastic things to wear, I have tried lots of different makes & they don't come close.
I went for 1 size up as they are supposed to be a snug fit, & they are sooo comfortable you really do think your wearing nothing.
Did a 1/2 in them with no rubbing or chafing. I will buying more also for presents for my running friends.
this is the 1st purchase of this brand, I've had issues with other brands with chafing in the past but absolutely none with the runderwear boxers, I just wish I had bought these sooner. they are absolutely great with no chafing what so ever and also they wick sweat so well. will definately be purchasing more.
I purchased 2 pairs of these mainly for their moisture wicking feature, which seems to work very well by the way.
I also found them to be amazingly comfortable and I just forgot that I was wearing them. It did take a couple of goes to get everything "in place", but then they were great.
So far, the longest run using them has been 2hr 30 - and they were comfortable all the way.
I have tried many things to ease the chafing - and mainly just “push through” and worry after. But after being recommended these by a Strava pal, I took a chance. FANTASTIC product - does exactly what it says it will. I’ve clocked some miles and NO issues!!! None. I’m training for the Dragons Back next year - so will thoroughly test...but so far; brilliant! Well done.
Running in them has completely eliminated chafing problems on long runs
They are very good, the only thing is that I wished I had ordered XXL instead of XL
Runderwear have great products which I use for all my training runs as well the two London Marathons I have run......Great value for money, great fit and really comfortable......
Amazingly comfortable and breathable. Looking forward to putting them through their paces.
My husband says these are very comfortable. Having read a previous review, I bought the extra large size whereas he would normally wear large. The decision was the right one.
Fit great and feels good.
Fabulous! My husband has raved about these boxers! Cool, comfortable and no chaffing! Very pleased :)
Great fit. Very happy.
Great product as an average runner of 10k distances. Looks small when taken out the packet but stretches easily and feels snug.
Good communication for delivery info and arrived in a couple of days.
I was a little apprehensive due to the overall size of the underwear and didn't think it would fit.
However, it was fine and comfortable to run in. Generally I have had under shorts which were longer than the actual shorts so it was a bit unusual so it felt like I had to keep pulling them down to stop the feeling of it riding down.
Though this is likely just a case of getting used to it.
Great customer service
Nice and comfortable though, optimised for running, and obviously well made. I doubt they'll make me any faster, but I certainly don't regret taking the Runderwear plunge.
They don't slip and start to fall down, which is nice. Perfect if you want to do parkrun safe in the knowledge that you're not flashing an unsightly builder's cleft at the person you've just overtaken.
Very comfortable-great to run or cycle in.
Brilliant product! Bought as I had 25% discount via Strava. Will be buying more. Good size, very comfy and work perfectly. I’ll be using them to run and for trekking.
Really pleased with my new Runderwear boxers, fit well, dead comfy and stay in place rather than bunching up like normal boxer trunks; and then there's the benefit from wicking fabric - least said!!
Only had these a few weeks but very happy with quality and fit
So comfy you forget you’re wearing them. No chafing so far either.
Just come back from a week of hot hiking around coast of Menorca in my Runderwear. I thought they would be a bit warm but they wick so well it really wasn't an issue and I could hardly tell I was wearing them. Wore them all week - quick rinse each night and dry and ready to go in morning. Only slight criticsim is they size a little small (I am a 30 inch waist but would go for medium next time rather than the small they suggest).
So far so good....worn twice. Once in torrential downpour where I wrung my shirt out before stepping into the house. Second time was hot and humid and the sweat was wrung from my shirt before stepping into the house.....no chafing in either case, so very impressed so far!! Having tried in two weather extremes, I am hopeful that the boxers will cope well with 'normal' weather!!
Don't know how I've managed without these in my life. Just come back from holiday, where every run was a sweaty mess, but never once had to worry about chaffing!
Done a few runs with these now and exactly what I was after. Not done over 14 miles yet but got a 34 miler planned in a month or so and I'm confident I'll still be able to sit down afterwards wearing these (it's the standing up again that might be an issue!)
Out of the pack they looked tiny but fitted fine. I tried them out with an easy 45k run and did forget I was wearing them. Definitely the best boxers I've tried for running. These are now my automatic selection for every run I do. I've now done speedwork, hills and long runs up to 5 hours in them and find them to be excellent.
I was sceptical at first, but took the plunge with boxers and a pair of briefs. The boxers, for everyday wear are superb. They stay in place, no rolling up the leg etc and keep everything where it should be (if a little snug). The top occasionally rolls down but that is because I am a fatty! The briefs are a joy to run in and for the first time I would consider buying shorts with no inner briefs and just wear these instead. A great product.
When removed from the packaging they're alarmingly small and initially I found them uncomfortable due to the snug fit. After a couple of runs I've got used to wearing them and having run a half marathon on a hot day without any chafing I'd happily recommend them.
Even better than their more expensive rivals. No chafing or movement or ride up
Very pleased with these.very comfortable.
After years of running, I can finally run without chafing. Having just completed a three day event, I would normally be in bits after the first run, but at the end I was completely chaff free
They do the job as expected, very comfortable
Very pleased with them.very comfortable to wear highly recommended
Great to wear.
Really comfortable and no chaff so far.
Would recommend them.
I have the briefs as well and have run several ultra’s in them and no chafing.
I got these underwear for the London marathon as I was worried about chaffing doing the long distance. With these underwear I didn’t worry one bit!!!
Purchased Runderwear Boxers ahead of London Marathon. Trialled them before on a short run and felt good, very comfortable and nice quality, but on the day itself they were just fantastic - running in +24C is not the most pleasant especially for that distance and with all the water that I was dowsing myself in to try and keep cool things could've got uncomfortable but the Runderwear stood up to the test and did exactly what was needed. Next up, 53 miles of Race to the Tower for which I don't see any issue.
Used this for my first half marathon race, really pleased with the quality and the comfort and dryness it provided. I’ve only just started using it, so not sure of endurance and life time, but judging by other reviews, with typical care it is definitely worth the investment.
Brilliant pants. No rubbing or chafing on any length of run. Couldn't recommend highly enough!
Honestly shocked how good these are I am so impressed. I brought two weeks prior to doing London marathon 2018 and did one long run in them and they were so comfortable. Ran London in them and had no issues I will no longer go anywhere else for my underwear.
Ordered these and the longer ones for some long runs. So far I've managed 18 and 20 miles without having to even worry about any rubbing "down there" before hand I was managing about 7 before I joined the 'Ministry of Silly Walks' trying to avoid pain and rubbing. Can't recommend enough! The best pair of pants you will buy!!
Why haven't I had these in my life before.
Was a bit worried when they arrived, they are so small.
But they are snug, comfy, and the reports of you dont know you are wearing them are spot on.
Big test will be in two weeks at Revenge of the Fifth, and the bigger test will be 4 weeks later at Race to the Tower !!!
Bought a pair for a race I had last weekend, and never knew I had them on. Very comfortable, no chaffing, great running underwear. Very pleased
I ran the Brighton Marathon 10K on Sunday & wore my new Runderwear Boxers for the 1st time on a 10k, i purchased these due to a major chaffing problem at the last 10K i did.
Well i have to say these were worth every penny as no chaffing at all so a BIG Thankyou to Runderwear.
Bought the boxers to go under my cycle shorts for some extra comfort/support and thanks to great design...especially being seamless...they worked a treat! So far have done rides of 80km with them on and nothing I can fault. Was a bit sceptical buying blind from the internet but this is definitely one of stories with a happy ending!
Superb. Gave me the confidence to run for a long time!
As comfortable as the briefs for sports use, just a little more high-waisted than I prefer. Seam free and they don't rub and chafe
Thought that these might be too short, but they’ve totally eliminated my chafing issues
whilst I appreciate that a long pair of boxers is available I found the length ever so slightly short. otherwise they are suprisingly comfortable. As previously mentioned they do look small out the box. I'd be interested to see how the next size up feels.
So comfortable you won't know your even wearing them. Used them for the first time doing back to back 63km and 52km runs with no hit of chaffing in the combat zone. I'll never run without them from now on
Prefer the brief to the boxer (slightly better fit for me). Received in good time. Thanks
These have been great for short distance running (up to 10k) however, after completing a slow ( 9:30 pace) 13.2 mile ( half marathon) run I found that I was getting rubbing (deep red sores) on the inside of my legs (just after 7 miles) though, not sure why this happened. I will be giving them another try out soon to see if the problem occurs again.
These boxers do exactly what it says on the add. I have been using them on my long marathon training runs and i didn't know i was wearing them . Great product highly recommend
Fantastic. Seam-free loveliness. Ran 30km in comfort with zero problems. Very, very happy with them.
Really good product that you can rely on. Very comfortable and wicking properties are very good too. Small margins make big differences and a little added comfort and no chafing is one thing less to worry about.
Love my new runderwear. They are so comfortable and fit perfectly giving support when and where needed.
Provided great support, very comfortable. No chaffing on long marathon training runs. Personally didn’t need to use any anti- chafing products. Very pleased and would highly recommend them.
Live and run in Bangkok and with the wet conditions I have always had problems with chafing so bad it would stop me running for days ! But there really are great and solved the problem for good
Bought the men’s boxers as a gift for partner. He’s very happy with them. He says they are extremely comfortable.
3rd time I've bought Runderwear. Great products and great service.
I ran a 33 miles with them. Really comfortable and no chafing at all. It solved all my problems!!
The quality is superb. Highly recommended.
What can I say? Does exactly what it says on the tin. Got boxer shorts for riding my bike (along with other clothing of course!) but with previous underwear it would push into less comfortable areas the further I rode Runderwear has silicone grips around the legs and is made from beautifully light and stretchy material - it's like a second skin and I'd highly recommend it to anybody, even if they're not athletic it's the most comfortable underwear I've ever owned
