Thanks to Kristen at StyleNik for the hot tip! It looks like local shoe-making guru Martha Davis is hosting a big sale over at Fab.com right now, entitling shoppers to more than 50% off her fashionable—and mega-functional—footwear. Prices for Davis' Twist Mules start at $173 (marked-down from $368), and other styles from spring 2011 and spring 2010 are up for grabs. Hurry up, though, because there's less than three days to redeem this incredible deal. In the meantime, learn more about Martha and check out her adorable Hayes Valley studio in our virtual tour!
