I am a big fan of Zappos.  The service has always been great — free and quick shipping, free returns and nice selection.  I love the new feature — Explore Zappos.  It allows you to see quickly a wide variety of shoes similar to the ones you have selected to view.  

Heres is a quick video to show you how it works (found at www.getelastic.com):
