Do you know what your shoe size is in Europe and Japan? Nope, neither do I. But it can be really handy information when you’re out thrifting or yard saling and you come across the perfect pair of shoes in a size that you’re not familiar with. Like these adorable French high tops that I spotted in a thrift store last year. I knew my youngest daughter would love them, but I didn’t know what her European shoe size was, and she wasn’t with me to try them on. I decided to take a gamble on them, and happily, they ended up being the right size.
