AC4 ACTIVE COMFORT SOCK

OS1st has launched the AC4™ Active Comfort sock, which features ultra-soft cushioning and SkinThin™ cooling technology. The company 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 constructed to endure long workouts while being just as comfortable working from home or relaxing on the couch.
