FAQ - What makes Runderwear™ the greatest running accessory in the world

What is Runderwear™?

Runderwear™ designs a range of seamless, moisture-wicking underwear for sport. The focus is on creating chafe-free products to increase comfort levels and reduce risk of rubbing and irritation.

What makes Runderwear™ different?

The Runderwear™ team only designs and constructs undergarments for sport, which means we can solely concentrate on being the best at what we do. Runderwear™ is engineered using 360 degree seamless technology, preventing nasty rubbing on the skin from irritating seams. Our range of Underwear, Socks, Bras and Socks all help you to stay comfortable and increase performance.

What materials do Runderwear™ use?

As we focus solely on underwear we are able to travel around the world discovering the best fabrics for our customers. Our underwear range is a blend of a highly technical moisture-wicking polyamide blended with a high grade of elastane for ultimate comfort and performance. The Merino Runderwear™ is produced using Merino Wool from Australian Sheep that are non-mulesed.

Tell me more about the company?

Runderwear™ is a brand on a mission; to create the best sports underwear in the world. The brand is the brainchild of two former Loughborough University students, Jamie Smalley and Rich Edmonds after running the New York Marathon and both suffering from chaffing. Launched in 2013 at the London Marathon exhibition, the product was sold out halfway through the show – making the Runderwear™ team realise that the product was innovative, unique and something people wanted.

“As competitive athletes we felt we couldn’t find underwear that matched up to the other clothing and equipment we were using to help us perform. It was like sportspeople just accepted that they would wear ‘normal’ underwear underneath their kit. We made it our mission to create a product that changed the world of what people wore underneath for sport.”

"We travelled around the world trying to source the best fabrics and machinery to make our dream become reality. We then spent two years sampling our products to make sure we had something unique that customers loved."

"We will constantly push down barriers to create the best sports underwear in the world."

Andy John said: Best socks ever!

Really pleased with the running sock, did a few 8 milers in them followed by 1/2 marathon.
Really comfortable to wear, and no blisters.
Looking forward to using them in the next 6 weeks, when I have another 3 1/2 marathons.

Nicola Hardie said: Fantastic buy

I bought these for my husband for running and cycling. He says they're fab with adequate support where it's needed.

Charl said: Wonder Woman should wear runderwear!

Runderwear is my go-to underwear choice for running, has been for a while, particularly for longer distances.
My recently ordered attire is actually even more comfortable than my previous, and the new design should make the vpl much less obvious, especially in the larger style of pant.

Dave said: check the sizing

Material is lovely and soft, and not a seam in sight, but despite ordering as per the size guide, I think I should have gone for the next size up as they were a bit snug around the leg holes! I did try them on over another pair of pants as suggested, but figured they were a bit snug due to to wearing two pairs!

I'll probably order some more in a larger size at some point.

Fozette said: Anti-VPL Low Rise Hipster

Very happy with my Runderwear purchases, having read the previous reviews I ordered these in a size Medium, I'm normally a size 10 and these fitted perfectly - so glad I took note of the reviews.

I also ordered shorts and socks in the same order and having recently had a birthday I suggested 'Runderwear' vouchers as present ideas but it turns out they're not available - such a shame.
