Mikaela Shiffrin's Must Haves Include a Pair of Cool-Kid Sneakers She's Loved Since Age 9

The Adidas Superstar Shoes ($100) have been a staple in Shiffrin's wardrobe for years. "These come with me everywhere," she says. "I'm kind of a sneakerhead and I have multiple pairs . . . I've been obsessed with the look and the shape of them since I was probably, I don't know, 9. All the cool kids at school always had their Superstars, and I was like, 'I want a pair.'" Despite her growing collection, this Adidas pair always get a space in her suitcase at the expense of other footwear.

Pro Tip: When it comes to styling these lifestyle sneaks, "everything goes," Shiffrin says. "I love a good dress and Superstar look, but I don't really bring dresses with me when I'm traveling for skiing. So I like boyfriend-style baggy jeans and a white T-shirt." Classic.
