...split toe socks. They're perfect for keeping my feet warm while wearing flip flops.
CKY got me a pair (pink with flowers), and I've worn them around the apartment all winter long. I'm tempted to start wearing them under my thicker socks for when I'm out and about, but I'm hesitant to cross that line. I'm worried that once I start doing that, it's a slippery slope to never throwing away newspapers, collecting plastic bags and hoarding cats.
