There's a fine line when it comes to shopping early. Nothing's worse than the sinking feeling of realizing something you wanted has somehow sold out before you've even had a chance to blink, but there's also the danger of splurging on something only to realize that you're not that in love with it when you finally do pull it out to wear. With a little bit of studying, though, it's entirely impossible to avoid the latter.
We scanned the full reports from each major city's fashion week to identify the shoe and bag trends  you'll start to see more and more. Read up on them all, and then strike out to shop with confidence.

Spring Shoe Trend #1: Ankle-Strap Pumps
The sophisticated single-sole pump has long belonged in the realm of polished, pulled-together professional women — aka the furthest thing from the vixen. But now with the addition of a sleek and skinny ankle strap, the pump has been injected with a dose of sex appeal. It's still sleek enough to wear at the office, but suddenly has new life for date nights and long nights dancing.

Spring Shoe Trend #2: Sheer
After seeing the parade of shoes that came down the Spring 2014 runways, we began to wonder if the next best thing to being barefoot is wearing a sheer shoe. A host of options presented themselves with netted mesh and see-through plastic, allowing for a peak of skin and a seriously cooling look. A leather bootie can add to the steamy factor on a hot Spring afternoon, but imagine how good a little breeze rushing through your heels would feel?

Spring Shoe Trend #3: Summer Booties
By now, the bootie's become such a wardrobe staple that it's hardly an exaggeration to say we're not quite sure how we could get dressed without it. And while we'll always love the look of a chunky pair worn with a light and airy sundress, there are times when we wished for something a bit lighter. It's as if designers read our minds, creating a variety of styles that had a bootie silhouette but flashed some skin by way of cutouts, peep-toes, and exposed heels.

Spring Shoe Trend #4: Mules
Like us, you might've associated mules with a retro trend better left in the past. Therefore, it was a happy surprise to see the sleek styles that paraded down the season's top-tier runways, adding an easy bit of polish to all kinds of looks. It's one of those shoes that's happily simple to translate from the runway and will work equally well in the office as paired with boyfriend jeans (and the shoes you can say that about are few and far between).

Spring Shoe Trend #5: Summer Camp
While there's nothing new about sneakers on the runway, the variety of styles we saw inspired by the sort of outdoor activities we did at Summer camp exploded this season. There were flat booties that looked eerily similar to water socks and strappy, nylon sandals that could've passed as classic Tevas. And sneakers. There were still sneakers.
