Important: please refer to the sizing chart in the image section to find the best sock according to your shoe size. Key features include: All-day Pain Relief: Stitch & Flow compression socks help to quickly reduce pain from plantar fasciitis, and provide firm but comfortable support for your foot and heel all day or all night long. Walk, run, and go about your day with ease. Also great for supporting recovery, improving blood circulation, and reducing inflammation all without restricting motion. Professional look, multi-pair combos: Solid black, white, and gray colors all available. Unlike other plantar fasciitis socks, ours don't have any crosshatch stitching patterns, and look like any other work-appropriate sock. No need to worry about questions from friends or colleagues - these socks blend in, and go well with professional attire. Additionally, we offer different combinations of colors in 2-pair and 3-pair packs. Buy in bulk and have enough pairs to last through the week! Extra comfy but supportive: Our breathable moisture-wicking material is made from a high-quality 80% polyamide / 20% spandex blend. Each pair is extremely comfortable and soft, and can be worn with any type of footwear or even under socks. Our open-toe design and 25-30mm Hg pressure level provide just the right amount of support and flexibility.
