Even with spring approaching, celebrities like Megan Fox and Selena Gomez have been using lingering chilly temperatures to show off one winter trend that just won't go away: Ugg boots. Last Friday, Jennifer Aniston joined the club when she ditched her heels on the set of "Murder Mystery 2" in favor of black zip-up booties (Buy It, from $130, amazon.com). While the fur-lined footwear might not have been part of her costume (that included a red dress and fishnets), they looked so warm and comfy. (BTW: If you haven't checked out Jennifer Aniston's new hair-care brand, you need to ASAP.)

The Ugg Bailey Zip Short Boots feature a rounded toe, a soft sheepskin exterior, and a groove-lined sole for traction. They're also lined with plush wool for serious coziness. However, what really sets the Bailey style apart from other boots is all in the details: With a tuft of fur peeking from the top and a gold zipper running down the side, the mid-height booties are like a dressed-up version of the classic Ugg, and they can elevate a casual outfit without skipping on comfort. Plus, they come in seven colors on Amazon, including unexpected shades, like bright red and blush pink (although Aniston went with classic black).

Shoppers swear they're both fashionable and functional. "These Uggs with zippers are so much easier to put on," said one, adding that they never felt windchill while wearing them, even in plummeting winter temperatures. "Worth every cent," wrote another customer who showed off pictures of their vibrant red pick. "Pure heaven on your feet," added yet another happy wearer. (Love comfy shoes? These are the best sneakers for standing all day.)

While waiting for spring flowers to blossom and the sun to finally come out, you can at least keep your toes warm by investing in an ultra-cozy boot. And whether you're on set or on the go, who better to look to for comfy style inspo than Jennifer Aniston? Check out her furry boots on Amazon or Nordstrom while they're still in stock.
