socks with shoes?

Wearing socks with shoes is a new trend at the high school (that - and bringing a blanket instead of a sweatshirt...weird, I know!), but this pairing makes sense to me! I should probably do this for sure to make sure my shoes fit just right. I may wear them for DAYS around my house - and I will probably buy flipflops because I am such a wimp when it comes to blisters!!
