I have seen the socks with sandals on Pinterest. Never saw anyone wear themin person, One sees them in old movies, and if you have any photos taken during WW11 when hose were made of silk, and not available as the silk was from Jsapan, women wore ankle socks with all kinds of footwear. Not sure if like with evening gowns, wtc. but one did see a lot of it with daytime dresses, etc.
Then there was the hippie era where sox were worn with the Birkenstocks, especially on men.
Personally I, being a very practical person, wear sandals to keep cooler in warmer weather, so socks would defeat the purpose. On the other hand if one were going form hot to cool like in traveling, easier to pack socks than extra shoes. I might wear them with cery casual walking sandals or something, like if in cold morning then hot afternoon.
