I dont like to see my feet too much, I not going to wear socks in the beach, shower, pool, etc. but i just dont like to see them. I dont mind other peoples feet. But back to the question, do you think wearing closed shoes or socks in the summer looks unattractive or weird/ugly?
God no, I don't think it matters... never once have I looked at a girl and been like "She cute... BUT THOSE CLOSE-TOED SHOES THOOO."... I wouldn't worry about it, people wear closed toed shoes all the time, whether they're lacking confidence in their feet, or if they're just active and on the go. No one's going to jump to the conclusion that its anything other than the second one either.
No. I don't like the look of sandals or flip flops period, no matter whose feet they're on. During the winter I wear boots and sneakers and during the summer I wear flats (even to the pool I wear plastic flats).
