• COMPOSITION: 80% Premium fabric 17% Polyester 3% Spandex

• STAY IN PLACE: The back grip keeps the sock in place and prevents it from falling under your foot. We tested hundreds of materials to make socks more stable before settling on the most healthy and comfortable silicone grips at the heel to help prevent sliding. Bacca Bucci awarded the STANDARD 100 label to all of our product's materials after they passed the test.

• INVISIBLE NO SHOW: These no show socks are ideal for people who wear shoes with any outfit. Also, the sock's top rises high enough to cushion the "tongue" of the shoe and protect your feet's skin from hard shoes; its height will never be too low or too high.

• ANATOMICALLY CORRECT FIT: The socks have a Y-Heel stitch so that it cups the heel for a better hold, and avoids the need for an overtight arch support. The elasticated arch band delivers just the right amount of snugness to feel confident all day long. The right / left specific socks further enhance the anatomical fit.

• ANTI-MICROBIAL PROTECTION: The socks are treated with an antimicrobial formulation which controls the growth of odor causing bacteria and increases overall freshness and hygiene levels.
