Two days into Paris' Couture Week, the biggest takeaway trend is the mid-calf boot. Spotted on the catwalks of Chanel, above, and Dior, below, this fresh new style boasts an easy-to-walk-in block heel, positioning it to be an uptown-to-downtown go-to. They were teamed mostly with mini dresses and skirts (another strong runway theme!), but would work with everything from casual jeans to elegant maxis. Its debut is timely, with all of us in the throes of winter-boot fatigue. Thankfully, there are some current options from Franco Sarto, Rag & Bone, and Tamara Mellon to add spring to our steps!
