SHYU performance running socks - the first & only socks designed to match the race day shoe they are worn with.

Our debut match for Saucony© is finally here. Made for their flagship Endorphin range including the Speed 4, Pro 4 and race-day favourite 'Elite' super shoes, we've created a colour that works across the range with subtle nods to the nuances of each of their launch editions.

Our lightest, fastest performance running sock made for the fastest shoe in your rotation
