Built on passion and rooted in a love for running, runderwear began when co-founder, Jamie, struggled to find performance underwear for the New York Marathon. Jamie suffered from bad chafing during the marathon (we’ve all been there!), and this was the moment that changed everything. Sick of having to compromise on comfort, Jamie and Rich were determined to find the solution – and so runderwear was born.

runderwear’s seamless, chafe-free underwear and blister-free socks are the most comfortable you’ll ever run with. No nonsense, no distractions and most importantly – no chafing or blisters. The runderwear range has evolved to include award-winning sports bras that have been meticulously designed and extensively tested to deliver the best possible results in comfort and support. Super-soft fabric is highly durable and incredibly gentle against your skin. The technical fabric also has excellent breathability and moisture-wicking qualities, meaning you’ll stay cool and dry.

Created by runners who get it, runderwear is built to endure the toughest of challenges. Whether you’re tackling a mile or a marathon, a parkrun or an ultra, you can count on runderwear for complete comfort. You will sweat, you will hurt, you will dig deep – but you won’t chafe. In fact, we’re so confident in our chafe-free products that we have a money back guarantee, not that you’ll need it!
