• Barefoot inserts size Small can be trimmed down to size. If between the available sizes, I think you could size up. These add a little arch support and just a tiny bit of thin padding that won't make your shoes too snug. • Amazon mesh flats size 6 I've worn these a lot over the summers. I'm normally a size 5-5.5 but they dont make my size. These don't have much padding / cushioning inside so I added the inserts. Travel , shoe inserts for kids and family LTKmomlife LTKTravel LTKKids
