Overview

The OS1st AC4 Active Comfort No Show Socks are designed to deliver cushioned comfort all day long. Featuring extra cushioning in the heel and toe areas, the socks are made from soft bamboo charcoal fibers for a highly comfortable fit. An ultra-thin Skin Thin™ panel along the top helps to promote airflow and regulate temperature for optimal breathability. Additionally, the seamless construction is treated with silver-ion technology to keep you dry and prevent odor. To prevent the socks from slipping down, a Y-Gore heel is integrated into the design.

    Great socks!These socks have just the right amount of compression, but still feel comfortable. I can’t say yet how durable they are with only two weeks wear, but so far they seem well made and aren’t coming apart anywhere. So I’ll give them a thumbs up there.
