The after-Christmas sales are in full swing, and as a shopping expert, I can go ahead and tell you that not everything is worth the time or money. That said, if you sit out other sales, I do urge you not to skip out on Zappos. Known as a premier shoe destination for everything from running shoes to high-end high heels, Zappos is always chock-full of good footwear. That said, today the goodies are on sale with an extra 20% on top of that!

We’re seeing jaw-dropping prices on Uggs, Hokas, Birkenstocks and more. Just use the code SAVE20 at checkout to save an extra 20% on select sale styles. It’s the perfect time to replace shoes you wore out this year or score pair you hoped would get discounted. Sizes are selling out fast (dang near faster than we could get this out to you), so you’ll have to move strategically.

To help you along, we’ve identified the 15 shoe deals that are worth your time and money. Grab them before stock dwindles or the deals end for good on December 29.
