The product has a flexible fabric; Product fabric composition: 62% Lambswool, 15% Viscose, 15% Polyester, 5% Polyamide, 3% Elastane; We recommend washing the product at 30 degrees; You can browse our store for more sock models; The products are manufactured by our company; Designed to meet women's need for comfort and style in both daily use and especially in sporting activities such as "Tennis," these socks are offered with an advantageous "3-Pack" option; This multi-pack provides the convenience of always having clean and ready-to-use basic socks in your wardrobe, either matching or different (although the color is not specified, the package may offer variety), while also creating an economical solution for long-term use; The lengths of the socks, specified as "Knee-High," "Half-Cuff," and "Long," indicate that they offer a fairly comprehensive length that effectively covers the calf and extends to just below the knee. This length can offer slight support to leg muscles, especially when playing tennis or other sports activities, and also provides extra protection against chafing that can occur inside athletic shoes.; The half-cuff length indicates that the sock comfortably extends to the middle of the calf, while the knee-high emphasis reinforces the classic athletic sock look and functionality of this length.; The "Basic" and "College" style emphasis indicates that these socks feature both a simple and timeless basic aesthetic and a sporty and youthful vibe inspired by classic American college sports teams.; The basic structure suggests that the socks may be plain or have minimal details, allowing them to easily match different sportswear and everyday clothing.; The college style, on the other hand, is usually characterized by elements such as striped details, specific color blocks, or a ribbed texture on the upper part of the socks.; This style detail adds a fashionable and dynamic look to the socks, going beyond just being a functional piece. The fabric's elasticity (though not specified, a comfortable, flexible, and breathable material is expected for both tennis and everyday use) allows the socks to perfectly fit the foot and leg. This elasticity prevents the sock from slipping even during sudden movements in sports, does not restrict freedom of movement, and ensures the sock retains its shape for a long time. This "Women's 3-Pack Basic Knee-High Half-Cuff Tennis College Sock" combines the timeless and sporty elegance of a basic and college design, the support and protection provided by its knee-high length, its ideal structure for sports like tennis, and the advantage of a 3-pack, offering women a sock option that combines performance, comfort, and style both on the court and in everyday life. It is designed to support foot comfort and the features needed during sports.
