How to fix cracked, dry feet INSTANTLY! I can't believe I haven't tried this before - it works unlike anything else I've ever done before! Just mix vinegar with Listerine and soak your feet for about 20 minutes (with hot water). Grab a clean cloth and wipe feet off. The dead skin cells will come off LIKE MAGIC! Repin this so you can do it later - it's a miracle DIY!
