They come up quite high so can show above leggings depending on design. Nonetheless, they are very comfortable and stay in place. I've had problems with knickers falling down during aerobic exercise, which was the reason for purchasing these, but they stayed put through a full class. Very happy.
Hey Louise,
Thanks for your feedback, Great to hear that you are loving your Runderwear Thong and they stayed in place during your Aerobic class. We love to hear this.
she really likes them, and finds them comfy for running longer distances, which she was concerned about.

Thank you for your purchases with Runderwear.
As a regular customer I took advantage of an end of line offer. These G-strings are perfect for wearing under shorts or leggings. They’re so light you’d hardly notice that you’re wearing them! Soft comfortable fabric with a snug but not tight fit. They keep their elasticity and softness after many gentle washes. The end of line garments had a slightly wider back string compared with the latest ones but they’re still a comfortable fit. Sold as ‘Women’s G-Strings’ but these should be ‘unisex’. Runderwear are definitely the leaders in running undergarments. I’ve not found an alternative manufacturer that makes such a good runners g-string.

Fits great and holds pretty well. Definitely recommended.

Love these. Really comfy and cushioning. No blisters but not tested on long run yet. Great for 15 km.

I used to get the most painful blisters especially during long runs, which would make even walking difficult. Since wearing these, I have not had a single blister. Seriously, these are amazing.

Can’t praise these enough. So comfortable, they make every run a pleasure.

These undies are a game changer for long distance runners.
Comfortable and snug they don’t move of chafe at all.

I’ve now purchased 4 pairs of these socks as they are so good at preventing blisters.
Ive got a 12hr run coming up and I will be using these socks without a doubt. So comfy and probably best used in colder times of the year as they are quite warm.

Used them for a half marathon and they were great. Generous sizing, no need to worry about large quads.

I bought the briefs and the shorts. These are amazingly comfy and definitely keep the moisture away so not rubbing. A revelation!

This is the only bra that doesn’t cut my skin when I run, and I have tried lululemon (very expensive) and sweaty Betty ( also expensive). They all give me so bad experiences, chafing bleeding, then I came to know runderwear through strava challenge with a discount. I haven’t look back, this is my fourth bras. Sizing is just my regular bra size.very comfortable.

These are so comfortable I’m seriously considering buying a pair for every day of the week!

This bra is amazing and the best that I have ever owned. I have been running for 19 yrs and over this time have bought numerous bras, I have had to run with straps digging into my skin and awful boob chafing. However this bra is completely different easy to put on super soft and so comfortable. The added bonus is the superb support that it offers whilst running. I will definitely be purchasing another one and hopefully some knickers…I would absolutely recommend this bra to friends and running buddies.

These socks are so comfortable: they keep my feet warm and cushioned from getting any blisters or rubbing on areas of hard skin.I use them for running and hiking and love them so much I got a pair of the mid length ones for colder days to come. Fantastic socks.

So pleased that I bought this top. It is comfortable and, like other runderwear products, keeps you cool and doesn’t ride up on even the longer runs. The material is so soft and feels luxurious.

Been running for over 30 years (not continuously 😂), and I’ve been through so many different brands and types of sock. These might not be the cheapest but you get what you pay for. So comfortable, great padding and compression and they look and feel amazing. Best. Socks. Ever. Trialled the 1st pair and bought 2 more. Wear nothing else now.

Never have I found a more comfy sports bra than Runderwear. Always struggled to find one that didn’t dig in on the shoulders, stop me from breathing around the rib cage and dislocating an arm when trying to remove this . Runderwear gives me none of those things and is super comfy from start to finish . Will be purchasing another one very soon.
