We offer more than one size, ensuring that our socks hug your feet like a glove. 2. We eliminated latex, which can cause discomfort for some, and we ditched the use of non-slip silicone because it only works for a short time. Instead, we modified the cuff design and used Lycra Spandex for its durability and elasticity. 3. To promote the comfort of your feet, we use high-quality materials, which may result in a slightly higher price. However, the benefits of our socks for your feet are long-lasting and will be noticeable over time, as your feet will feel smoother. 4. The black part on the soles is made of high-quality combed cotton, a natural material with a somewhat loose structure, resulting in some black lint on your feet.
