So you found an amazing pair of shoes online for an even more amazing price. Seriously too good to be true. They only have one size and one color left in stock but it happens to be your size 7 and your favorite blue. You enter your tracking number every hour online like a crazy person because you can't wait to leave work early to tear open the box. They arrive, you throw the wrapping aside and wait for the heavenly chorus to sound as you slip them on... wait... you can't get them on... no! they're too small!

I'm certain that anyone who has bought shoes online has had this problem. The simple fact is that different shoes fit differently; not even all Marc Jacobs brand shoes fit the same way, let alone all boots or all ballet flats from different brands. But buying shoes online does not have to be a 50/50 game of chance anymore. Here are some great ways tip the scale in your favor:

1. When you see a pair of shoes online that you love, first check your closet to see if you have any shoes by that brand already. Fit may vary by style but it's more likely that it won't, so it's always a good idea to take note of the sizes you've been wearing in that brand. If you've never bought a shoe from that brand before, you may want to stop at a department store to try on one or two styles to get an idea about how their shoes work on your feet.

2. Many websites allow customers to write reviews on shoes they have purchased from them and there are other websites devoted entirely to reviews. Even if you have 20 pairs of shoes by a specific brand all in the same size, you may still want to check reviews to see if that one style fits a little small or big just as a fluke by the brand. If you're not sure how to find a review, search on an internet browser like Google or Yahoo for the brand name, style name and the word "review" or "reviews".

3. You may also want to try researching the brand of the shoes you're interested in to see how they list their sizes on the shoes themselves, whether they are in US sizes (like 8, 8.5) or EURO sizes (like 39, 40) or some other size like German or Japanese. Usually a brand will not change their sizing between styles. This will help you especially when buying European shoes as some websites will only show you the converted US size (if you are a US shopper) which can be incorrect. Always ask what size is printed on the shoes themselves and base your fit off that size.
