Honestly, I’ve been there too, and the difference really comes down to material and fit. For nighttime warmth without bulk, soft natural fibers like alpaca are amazing because they’re lightweight, breathable, and naturally insulating. I actually picked up a pair of Alpaca bed socks and noticed my feet stay comfortably warm all night without sweating or feeling cramped. The key is to look for socks with a bit of stretch that hug your feet snugly but don’t restrict circulation. Pairing them with a cozy blanket and keeping your room at a slightly cooler temperature surprisingly enhances warmth even more.
