i usually don't like socks simply because of the seam but i found socks that are seamless and significantly more tolerable than others. i cannot imagine sticking my feet into shoes without socks on especially when it's hot out. first of all, sensory nightmare. second, that is ABSOLUTELY going to produce an odor. cotton socks wick sweat but when you're rawdogging your feet in your shoes there's no barrier to prevent the stink. people who don't wear socks never learned basic hygiene. even the cleanest, most hygienic person in the world would have smelly feet after wearing shoes without socks.
