If you like to wear flip flops all year long, you need to put flip flop socks on the top of your holiday wish list.
Etsy has recently exploded with crocheted flip flop socks, which are basically toe-less and heel-less socks that allow you to wear flip flops and keep your feet relatively warm. They are also pretty great for going to yoga during cold months.
They cost a little over $20 each and come in every color imaginable. (Good Housekeeping)
