The Buttons & Pleats Merino Wool Socks are designed to keep your feet warm and comfortable during cold weather. Made from a blend of merino wool, acrylic, nylon, and spandex, these socks offer a soft, itch-free experience thanks to the gentle merino wool, which also helps regulate temperature so your feet won’t overheat. Their thickness is on the heavier side, providing excellent insulation for winter use.

The socks have a regular fit that suits most foot sizes, with added arch compression for support and to prevent slipping, making them suitable for active wear. Cushioning is well thought out, featuring a fully cushioned footbed as well as reinforced toes and heels for comfort and long-lasting durability. Breathability is addressed through moisture-wicking properties and mesh ventilation channels that help keep feet dry.

These socks are relatively thick, which could feel bulky in tighter shoes. The height suggests they are boot socks, likely covering the ankle and lower calf, making them ideal for winter boots.

The socks also feature ankle vents to reduce bulk and improve breathability, helping to keep feet dry by wicking away moisture and controlling odors. The thickness and cushioning, while excellent for warmth and comfort, might make the socks a bit bulky for those who prefer a thinner fit or want to wear them in tighter shoes.
