If you love shoes then you must check out endless.com. There are several reasons for this site’s awesomeness. First, there’s no charge for shipping, to you OR from you (returns). Second, they have a bunch of useful filters for finding the exact shoe you are looking for, such as color, size, heel height, type of shoe, brand, etc. Third, you get the shoes one business day later, which I find terribly convenient. To me this is so much easier than getting my lazy ass to the store and hoping they have the shoe I’m looking for. I see no harm in buying three pair and returning them all – they just make it that easy.

And from a UI perspective I think the site is very easy to use.
