If you have Birkenstocks or a similar kind of sandal/shoe with cork material in the sole, this will extend the life of your shoes DRAMATICALLY. You can buy cork sealant at a shoe store, hardware store, or online for around $5. Whether your sandals are brand new or a decade old β like mine β this will breathe extra life into them with not a lot of money or effort.
As an added bonus, painting on the sealant is a very calming summer activity.
