ALLIED X SockGuy SGX Race Day Socks

We don't know who originated the phase, but we totally agree: Socks make the man. And SockGuy is tops when it comes to both function and fashion, which is why we chose them to produce custom ALLIED socks.

The SGX Race Day blend is designed with the elite athlete in mind with its blend of PolyPro, nylon and spandex. It provides a compression fit, performance ribbing, enhanced ventilation and a reduced friction profile. These socks feel great, look great, with SockGuy's signature Stretch-to-Fit sizing and reinforced toe & heel.

Sizing is pretty straightforward: Choose S/M if your shoe size is Men's 9 or smaller (42 or smaller Euro) or Women's 10 or smaller. Choose L/XL if you're 9+ in Men's, 10+ in Women's, and 42.5+ in Euro.
