Still wearing flip-flops even as temperatures take a dive? Apparently, you're not alone.

According to WTVT, a new trend is sweeping online stores – flip-flop socks.

Etsy seller Sophia Vernava of Sew Darn Comfy said her handmade version of the socks, which leave the heel and toes exposed, are flying off the virtual shelves.

"I can't keep them in my shop. I list them, and in a few days they are snatched up," she told WTVT, adding that the socks are popular with dancers and people who do yoga and Pilates.

If you want to add a pair to your wardrobe, similar items are available from other Etsy shopsAmazon and eBay.
