Patent

Simple – but only on the surface

Our socks may appear simple on the surface, but behind the simplicity is an intricate system of targeted compression, anatomical design and seamless toe that makes our products particularly innovative. To inspire a healthy, active lifestyle, we must continue pushing the envelope of what is thought possible to develop products that help you achieve your best. 

Because these inventions require such substantive investments in research and development, we must protect ourselves through patents. Patents give us a timeframe where we can build a business and recoup the investment without being unfairly copied. And lets face it, copies are often unreliable and poor performers.

Building Trust through Quality and Innovation

We have established a trust in the market as being the leader in high performance socks, and our innovation has been a large part of that trust. In no small part thanks to our Product Designers, we look forward to providing innovative solutions long into the future.
