Are alpaca socks warmer than merino wool?

Alpaca is generally warmer for its weight and softer, but merino dries faster and handles repeated washing more predictably. For deep cold and comfort, alpaca wins; for wet, high-output days, merino is the safer pick.

Will these fit inside hiking boots?

They are a thick sock, so they suit roomier boots and winter footwear. In snug or low-volume boots, size up the boot or wear a thinner sock.

Do they itch like regular wool?

Alpaca fiber is smoother than sheep's wool and is usually described as non-itchy. Sensitive skin generally tolerates it well.

How should I wash them?

Hand wash or use a gentle wool cycle in cool water, then air dry flat. Heat and tumble drying can shrink and mat the fiber.

Are they good for skiing?

Yes, as a warm base layer inside ski boots. Their thickness means you should check boot fit first, since a tight boot reduces circulation and defeats the warmth.
