Sock Geek Says:

Looking for a high performance running sock that delivers on the roads and is friendly to the environment?  Try the NBx Cocona sock from New Balance.

Cocona is a renewable and sustainable fabric made from activated carbon generated from coconut shells.  Cocona offers superior moisture management and natural odor repilency.

Left/Right engineered for anatomically correct 2nd skin fit.  Arch support adds stability and comfort by keeping fabric in place.  Strategic cushioning -- selectively cushioned to provide essential shock absorption in strike zones.  Seamless toe for comfort.  Mesh fabric for breathability.  Extreme abrasion resistance. "Y" heel -- deep pocket for perfect fit.

Truly a well fitting and comfortable lightweight run sock.
