Honestly, natural fibers like wool or alpaca are usually the best for warmth and breathability, and they tend to last much longer than cheap synthetics. For something that really combines softness with durability, I recently came across alpaca Mohair socks, which feel incredible on and don’t irritate the skin at all. You can check them out at alpaca Mohair socks — they’re surprisingly cozy and perfect for keeping toes warm during long walks or at home. It’s worth investing a bit more for comfort, especially in winter.
