Pictured: The Swiss Barefoot Company's FYF socks being worn outside.
An ultra-durable waterproof sock made from material 15 times stronger than steel could replace the common trainer for athletes taking on virtually any sport. The revolutionary FYF sock by the Swiss Barefoot Company - named after 'FreeYourFeet' - fits like a glove and can be used on any surface.
It uses a fabric called Dyneema, an extremely strong and durable fibre that floats on water and is resistant to moisture, UV light and chemicals. SEE OUR COPY FOR DETAILS.
