Socks are like little coverings that you put on your feet to help keep them warm or protect them from rubbing against your shoes. Sandals, on the other hand, are shoes that have openings and straps to let your feet breathe and feel cooler.
When people wear socks and sandals together, it means they put on socks first, and then they put their feet into sandals. Even though socks and sandals seem like they shouldn't fit together, some people like to wear them that way because it makes their feet feel more comfortable or because they think it looks stylish.
Some people might not like the look of socks and sandals together because they think it looks silly or like someone is trying too hard to be fashionable. But it's important to remember that everyone has their own style, and what might not look good to one person might look great to someone else. So if you want to wear socks and sandals, that's totally okay!
