OS1st launches the AC4 Active Comfort Sock

HICKORY, N.C. – OS1st created the ultimate comfort crossover between the ultra-thin TA4™ ThinAir sock and the ultra-plush WP4™ Wellness Sock to create the new AC4™ Active Comfort sock with enough cushion, ventilation, and protection for any activity.

The AC4™ is constructed with a deep, Y-gore heel pocket, anatomical left/right design, and OS1st’s signature C-Zone™ Technology that uses varying levels of compression to achieve the best fit possible while providing arch support. The double tabbed sock top is designed to prevent blisters and slipping.

Made with anti-microbial silver-ion treated micro-fiber nylon and naturally moisture-wicking nano-bamboo charcoal fibers on 200-needle machines, the AC4™ Active Comfort sock is exceptionally constructed to endure long workouts while being just as comfortable working from home or relaxing on the couch.

“This is our Goldilocks addition to the Socks with Purpose™ collection,” President of OS1st, Josh Higgins, said. “The SkinThin™ panels and the nano-bamboo charcoal cushion blend perfectly for a go-to sock with a simple purpose – being “just right” for every activity.” 

The AC4 Active Comfort Socks are available for wholesale pre-order and will be available for shipping and consumer ordering on May 1.
