Are these socks warm enough for winter?

They are a light winter sock. With 12% wool and 35% cotton they add warmth for cool days and mild cold, but they are not a heavy thermal sock for deep winter or outdoor work.

What is the material blend?

About 35% cotton, 12% wool and 1% elastane, with the rest making up the balance. The cotton keeps them soft and breathable, the wool adds warmth, and the elastane gives stretch.

Do they fit all foot sizes?

They come in one size only, listed as small to large. That covers most adult feet, but people with very small or very large feet may find the fit loose or snug.

Can I wear them with Birkenstock sandals?

Yes. They are designed to pair with Birkenstock sandals and clogs, and the crew height sits above the footbed strap line.

Are they itchy like pure wool socks?

Most people find them less itchy than pure wool because cotton is the main fiber. The wool content is low, so the scratch factor is mild.

How should I wash them?

Wash gently, ideally cold and inside out, and air dry to protect the wool and elastane. Avoid high heat, which can shrink the wool and loosen the stretch.
