Even after her morning workout, Kim Kardashian looked super stylish donning a leather-sleeved Generation Love Bobo sweater ($171) and black and white Nike freestyles ($100) in Miami. Kim's leather-accented sweater proved her love of leather extends far beyond everyday ensembles and red-carpet looks. The trendsetter completed her sporty style with a high ponytail, aviator sunglasses, and a tan suede tote. Score Kim's exact textured topper to work with these burgundy Earnest Sewn skinny jeans ($178) and ballet flats for a day of errands or tuck it into this tweed Milly mini ($295) with black suede ankle boots for an evening out.

When your day revolves around online shopping — rifling through the virtual racks, checking out the latest collections, styling the latest trends — it's impossible not to actually shop when your job depends on knowing what's what in fashion. Naturally talk at Fab quickly turns to what everyone's been shopping (especially when the purchaser shows up to work with her new piece). Lately, that's high-tops. From style director Noria Morales's sweet white Isabel Marant lace-ups (a recent acquisition from Paris Fashion Week) to associate editor Chi Chau's Marant high-top addiction, this season's obsession with sneakers has spread to Fab HQ. If you're on the fence, here's what made us high-tops fans: first, models, fashion insiders, and celebrities showed off designer iterations of the old-school favorite with a fresh twist, and now classics like Nike are giving their versions a stylish update with Liberty florals and colorful finishes. The best part? These kicks are as comfortable as they are cool (if you can wear them at Fashion Week, you can wear them anywhere), and they're the perfect alternative to Fall ankle boots. Click below to shop the ones we're loving right now.

With half of the 2012 Olympics over, we've seen more than a few heartfelt medal ceremonies in London. And besides the cheers, tears, and patriotism, many of the athletes on the podium have another thing in common: bright neon green Nike shoes.

Those bright shoes are the Nike FlyKnit Trainers, part of Nike's US medal stand footwear and apparel collection. The lightweight shoes are made of eco-friendly material and designed to fit and feel like socks. Earlier this year we got a sneak peek at the new technology; read what we learned about the minimalist FlyKnit and other Nike Olympic apparel and footwear. The Nike FlyKnit Trainer+ ($150) is available in 10 colors here.

While promoting their new flick Snow White and the Huntsman in Madrid, Kristen Stewart and Charlize Theron coordinated their all-black outfits down to their old-school Converse and Nike sneakers. We all know Kristen is a huge fan of comfy-cool sneakers, and we love how her red Converse Chuck Taylors ($50) livened up her dark outfit, which included her go-to quilted leather Balenciaga jacket and a black Joe's Jean tank ($88). As for Charlize, we're used to seeing her in edgy heels, so the black-and-white Nike low tops ($35) she wore were a refreshing change. Plus they lent sportiness to her otherwise-classic ensemble. Score Kristen's and Charlize's exact sneakers, then be sure to add them to your everyday outfits for a comfy-slash-sporty flair.
