Treat Yourself With Our December Must Haves

I've run several races in various Adidas Boost shoes — which all feature a bouncy, responsive foam sole — and they never disappoint; you can really feel the extra bounce in your step, mile after mile. Expect the same quality experience from the newest version of the Adidas Ultra Boost ($180), which improves on the previous version with a flexible yet supportive Primeknit upper and added outsole traction.

Between battery-draining habits like using Spotify during my runs or using GPS to find my way to a new workout studio, I always need to have an iPhone charger on hand. The Lander Neve Lightning Cable ($22, originally $30) is made for camping — its rugged, no-tear material reflects in low-light situations so you can find it easily at the campsite — but I like it just as well as an extra cable I can easily grab when I'm frantically searching through my purse.

Ever since I moved from hilly San Francisco to much flatter Brooklyn, I've become even more obsessed with city biking — thanks in large part to my Priority bike. Started as a Kickstarter campaign just over a year ago by bike-shop veteran Dave Weiner, the company's goal is simple: make high-quality, affordable, and beautiful bikes for the most discerning beginner cyclist. If you've ever stepped foot into a bike shop and been overwhelmed by the choices of frames, gears, handlebars — you name it — you'll know that choosing a bike can be an intimidating process for the inexperienced (trust me, I've been there). Priority makes the process simple: choose from two different types of frames and sizes, then pick your color. The three-speed Priority Bicycles Classic ($430, originally $450) has taken me across New York City for fun, work, and errands with barely more than an occasional tire refill, and it's lightweight enough that I can carry it to my third-floor walk-up apartment with ease. I've been recommending it to all my friends as the perfect entry-level bike for the casual commuter at a surprisingly good price point.

Brrrr! If chilly weather isn't keeping you from running or biking outdoors, then you need layers to keep you warm. This Mizuno Full-Zip Hoody ($85) is made with Breath Thermo technology, which actually generates heat for added warmth. I wore this over a sports bra and tank on a 30-degree run and it was perfect. The hood keeps your head toasty and is able to slip down when you get too hot. The thumbholes prevent wind from going up your sleeve, and I love that the zipper goes all the way up to your chin. This is also going to be a great baselayer for under my Winter coat when snowshoeing or skiing. Definitely worth it!

Staying active outside is vital to beating the Winter blues, but you have to be properly dressed. I love this Stripes Reversible Dome ($26, originally $35) from Mountain Hardwear for my wintry activities. It's perfect for hiking and cross-country skiing but also cute enough to sport on my commute. And since it is reversible, it is really two hats in one! Go solid when the mood strikes, or make it stripey for extra splashes of color.

Fancy dressing during the holiday season is no longer limited to the LBD for formal occasions! These stylish Motopant leggings ($74) from Onzie turn any workout into a party. And, of course, they make hot yoga even hotter. The mesh panels on the thighs and calves help keep me cool during yoga and SoulCycle. These leggings are eye-catching outside the studio too — pair them with a tunic and short boots and you're ready for post-workout weekend brunch.
