F4 Blackout No-Show (3 pair pack)

$25.00

FS410-001-01

Check it out - The BLACKOUT F4 3-pack from Fitsok! It's the darkest and fastest F4 we knit.

Designed to meet the demands of race-day athletes, the F4 utilizes to provide compressed venting and moisture wicking in the most extreme conditions. Made with Sorbtek®, this sock channels moisture away from the foot, keeping it cool and dry. Anatomical left-right foot construction allows for precise fit, while a unique cushioning system provides comfort in specific pressure areas. Achilles protection reduces blistering on the back of the foot, and a front tab protects against shoe friction. The F4 is only available in no-show length.

Each 3-pack is fully blacked out.  These socks utilize all the same engineering and tech loaded into our standard colors. They’ll keep your feet looking as fast as they feel. Available for a very limited time.

83% Nylon, 16% Sorbetk Polyester, 1% Spandex

The socks are great! The only issue I had was that the order (#14913) was short one pair of the CF2 qtr black socks and I still haven’t received the missing pair.
