Barefoot sandals originated in South Asia where they were used purely as decoration at festivals and events. The good thing is that they can be made out of pretty much any material you can think of: ribbon, hemp, beads, gemstones (non-sharp!), wood, or yarn. Just be sure not to use any metals if you'll be out in the sun. They can get hot and burn your tootsies. So check out this eye candy to inspire you to think outside the shoe for a beach or forest wedding, or if your wedding shoes need some pieces of flair.
This tutorial from Youtuber Mikeyssmall uses thin yarn and beads. The measurements seem useful for any material though. Let us know if you end up wearing barefoot sandals or even DIYing your own.
