Amazon, Zappos, Nike, Adidas, and Reebok. According to our highly scientific and completely unbiased (cough, clear throat) study, these are the five best places to buy running shoes for women.

We took into account a number of factors, including price, selection, customer service, and ease of use. We also read through countless reviews to get a sense of what real customers thought about each site. In the end, we came up with five clear winners. Here they are, in no particular order.

#1 Amazon

Amazon is a great place to buy running shoes for women for a number of reasons. First of all, the selection is incredible. No matter what type of running shoe you're looking forβ€”stability, motion control, minimalistβ€”you can find it on Amazon. And with Prime shipping, you can usually have your shoes in two days or less.

The prices on Amazon are also very competitive. While you can sometimes find a better deal elsewhere, Amazon's vast selection and convenience make it a great place to start your search for the perfect pair of running shoes.

Finally, Amazon has amazing customer service. If you're unhappy with your purchase, you can return most items within 30 days for a full refund. And if there's a problem with an orderβ€”say, your shoes arrive damaged or the wrong sizeβ€” customer service will work with you to ensure that you're satisfied with your purchase.

#2 Zappos

Like Amazon, Zappos has an impressive selection of running shoes for women from all different brands. However, what sets Zappos apart is its customer service. Zappos has a team of experts who are available 24/7 to answer any questions about sizing, fit, or style.

Zappos also offers free shipping and free returns on all ordersβ€”no matter how much or how little you spend. So if you're not sure which pair of shoes is right for you or if you're worried about ordering the wrong size online, Zappos is a great option. You can try on as many pairs as you want in the comfort of your own home and return anything that doesn't work outβ€”at no cost to you.

#3 Nike

If you're looking for a specific brand of running shoeβ€”say Nike or Adidasβ€”it's often best to go straight to the source. When you buy from Nike or Adidas' websites, you know you're getting authentic products direct from the manufacturer. You also have access to the latest styles and technologies from each brand as they debut.

Nike and Adidas also often offer free shipping and free returns (though sometimes only on orders over a certain amount). And if neither of those options is available at the time you're shopping, both brands have brick-and-mortar stores where you can try on shoes before making your purchase.

There are a lot of great places to buy running shoes for women onlineβ€”but these five sites are our favorites. Whether you're looking for amazing customer service (Zappos), free shipping and returns (Nike), or simply the best selection (Amazon), one of these sites is sure to have what you're looking forβ€”at a price that's right for you.
