But boots are only breathable when you're wearing technical socks. Whereas cotton socks absorb and store moisture, technical socks first of all wick sweat and moisture away from your feet and into your shoes. Then the breathable shoe membrane completes the job of transporting the moisture out of the shoe altogether. That's how breathability works.
