All new! This spin on our classic Nylon eliminates the toe seam in the toe box of the sock, creating a “seamless” feel, much like ourCottonandMerino WoolCompression Socks. Made with high-quality fabrics and 200-needle count for comfort and style. This different knit provides a softer feel while still utilizing our custom Nylon Blend. Our socks offer moderate-firm compression (20-30 mmHg). 20-30 mmHg is considered medical-grade compression and generally recommended or prescribed by your doctor. This design also comes in15-20 mmHg.
