Runderwear Cushioning No Show Running Socks

Good service, product is fit for purpose

Service is great, and the boxer shorts are good for running and so the job they are designed for. Little disappointed that they are not ethically sourced, they have a cheapish feel to them which was a surprise.

Thank you for your feedback Duncan. Runderwear's range of seamless underwear has sustainability benefits over cut and sew garments by reducing wastage of fabric at manufacturing stage. We are testing new fabrics that have been made using sustainable fibers and aim to bring these into our range in the near future. All our factories are quality control checked to the highest standard and our small team regularly visit them and are satisfied that working conditions are ok. We are somewhat surprised you find the pants have a cheapish feel to them. But maybe you mean that the material is not thick and when you stretch it and look up-close it has an almost gauze-like appearance; this is the nature of the product and gives it the moisture wicking properties. We hope you will like using them and will realize how comfy they are.

Women's Running Long Shorts

At last... chaff free running.

Had just about given up with the belief there were running shorts out there that don’t chaff. Purchased the long shorts, and have to say they are wonderful. They are stable, breathable, comfortable and total chaff free.
I would like to highlight I was under the impression that these were “proper” shorts, however they could possibly be described as a base layer shorts. Some form of lightweight run shorts are recommended to wear over them to cover your modesty. Wearing my lightweight run shorts over the top of them didn’t detract from the long shorts benefits.
I typically run up to 21km.
