Toms One for One Ballet Flat Size 8

Toms ballet flat size 8 in very good condition! The only flaw I can see is a mark showing where an insert had been in the shoes. It’s not sticky or anything like that, but you can see it in the photos, and I wanted to highlight this flaw that will not affect wear. Inside the shoe, There is a letter next to the size, but I can’t tell if it’s 8 M, or 8W.
