To keep our mind on our line and off our feet, we pull on the Darn Tough Function X OTC Midweight Cushion Padded Shin Sock before tugging on our boots. The underfoot padding helps absorb vibrations and shock, while the super-thin upper foot panels reduce bulk and boost airflow for optimal comfort. When the terrain steepens and our angles get more aggressive, the upper-leg cushioning pads our shins to reduce the pressure from our boots.
