Here are some of the best materials for keeping your feet warm in winter socks:
Natural Fibers:
Merino Wool: This is the gold standard for winter socks, offering excellent insulation, moisture-wicking properties, and odor resistance. It's soft, comfortable, and naturally regulates temperature, keeping your feet warm when it's cold and cool when it's warm.

Synthetic Fibers:
Acrylic: A more affordable alternative to wool, offering decent warmth and moisture-wicking properties. However, it is not as breathable as wool and can become uncomfortable if you sweat a lot.
Acrylic winter socks
Polyester: Similar to acrylic, but not as warm. It is often used in blends with other fibers to improve durability and moisture-wicking.

Blends:
Wool blends: Blends of wool with other fibers, such as polyester or acrylic, can offer a good balance of warmth, affordability, and durability. Just make sure the wool content is high enough to provide good insulation.

Other factors to consider:
Thickness: Thicker socks will obviously be warmer, but they may not be as comfortable in all situations. Choose a thickness that is appropriate for your needs and activity level.
Length: Crew socks, knee-high socks, and even thigh-high socks can all provide different levels of warmth and coverage. Choose a length that is comfortable for you and that will keep your legs warm as well.
Seam type: Flat seams are more comfortable than linked seams, especially for people with sensitive skin.
Ultimately, the best material for keeping your feet warm in winter socks is the one that works best for you. Consider your individual needs and preferences when making your choice.
