You’ve heard it before – new year, new fitness regimen. But before you hightail it to the treadmill, make sure you’re outfitted with kicks that fit with help from these quick tips.

Learn Your Foot Type. The best way to discover whether you have flat or high arches (or lie somewhere in between)? The wet test. Pour a layer of water onto a cookie sheet, step into the water with a bare foot, then step onto a piece of heavy paper. Decode your results and peep the full how-to here.

Then Outfit Accordingly:

High arches. This means you likely roll your feet out, or underpronate, when you run. Look for running sneakers that offer cushioning or flexibility.

Flat feet. Your feet probably roll inward (or overpronate), which means you’re best off with running sneakers that offer motion control and stability.

Normal (or medium) arches.  You can wear just about any shoe (jealous!), so take your pick of the litter – and have fun with colors, trends, and styles.

One of the most common New Year’s resolutions? Getting in shape (just check out all the Pinterest boards dedicated to it). Well I, for one, am determined to make it happen this year – and luckily I have a secret weapon. From fun sneaks and a cute duffel to flattering, lightweight workout clothes, resolving to get fit seems easier (and more stylish) than ever.

The Shoes
With a bright, breathable mesh exterior, these running sneaks double as oh-so-cute commuter shoes.

The Clothes
A tank with a built-in supportive bra and sleek running tights (the perfect alternative to baggy shorts or sweatpants) are the gym clothes you won’t mind being spotted in.

The Bag
Not too bulky but big enough to fit sneaks, makeup, and a change of clothes, this athletic bag makes it easy to get all your gear to the gym before or after clocking out.

While my life is dedicated to style, I have to say it: you can not pick running shoes based on color. Each shoe is designed with specific runner mechanics in mind. The prettiest colors may not always give you the right type of support or flexibility you need. Make up for it by buying fun running clothes or getting a great running buddy.

I recommend you go to a running shop and get fitted. A good place will analyze how your feet hit the ground, ask you about trouble spots (like knees), and recommend shoes based on these (and other) factors. The store should let you test the sneakers, and have a pretty good return/exchange policy. The fitting is free, and the time spent up front will avoid time spent at the doctor’s or physical therapy later.

After you get fitted, once you find the pair of your dreams, stock up! I now buy mine two at a time (yes, on Rue). My favorite pair of sneakers got an update after I bought them, and I was never able to find the older style again. I’m kicking myself as I write this for not buying four pairs when I had the chance. You can usually get 300-400 miles on a pair of shoes – once you start to feel old aches starting to resurface, you should already be breaking in a new pair.

Your running shoes should be about one size bigger than your street shoes. Feet swell when you’re running, and tight sneakers are a great way to lose toenails. Buy ’em bigger to avoid having to tip 50 percent on your next pedicure (and grossing out your friends and family).

To avoid blisters, wear a blended sock (cotton ones still rub) and break in sneakers a couples miles at a time. This will also help you avoid an awkward limp in your work shoes, or worse, a trip to the doctor’s. (I’ve been there. It ended with a lot of gauze.)
