If I'm at home, then it's bare feet all of the time, all year round. If I'm in the home or back garden, you won't ever find me wearing shoes or socks, regardless of the weather.
To go out, I wear flip-flops for as much of the year as I can.
I'm self-employed and WFH 100% which dates back to 2010, so no need for work attire.
I do have a variety of shoes/boots/trainers that I wear if I need to leave the house and it's not flip-flop weather. But they're on rotation so don't ever seem to get smelly. I have washed shoes in the washing machine before. We have several people in the house who are extremely sensitive to smells, myself included, so it's something that I'm very vigilant about. DP's latest slippers bloody stink so we are quite sensitive to smelly feet!
Buying decent, good-quality shoes that don't make your feet sweaty seems to help. Also, I'm normally only out of the house for 2-3 hours at a time plus there are long gaps between wearing the shoes, so probably they don't have the chance to get smelly!
Due to circumstances at home, I've not taken part in sports for the last few years or gone hiking - and I would have needed socks for either of those activities. I'm hoping to get back into racket sports later this year so probably need to get some socks at that point. The thought of wearing socks though makes me feel very uncomfortable so it will be a necessary evil! 😅
