I didn’t think they look amazing together but I can see plenty of reasons as to why someone might want to combine them.
Socks can prevent chafing
Socks can prevent debris or dirt getting onto foot & under toe nails
Socks can keep feet warm if weather changes
Socks can keeps sweat from collecting in sandals if it’s hot,
Some people prefer sandals in cool / cold weather so of course you need socks.
Sandals can be way roomier than shoes & even with socks in, snarls can be far more breathable.
Weirdly, i’ve seen people get mad saying the purpose of sandals is ruined if you wear socks & sandals and insist you should just wear shoes if you want to cloister your foot but as I said it’s different with sandals than shoes…. There’s a different comfort level. It’s as if they are trying to not recognize this and I didn’t get it.
Anyhow none of that explains why anyone would get upset at sod one else’s foot wear choice lol like it’s not your feet, chill 😂 🤦🏻♀️
