Last week I bought LO a pair of silver Emi Smaller shoes. She's worn them 3-4 times, and the silver is already rubbing off of the toes. She doesn't even walk yet, so it's not like she's hard on shoes! I'm so disappointed... Especially since SKRs aren't cheap. Am I expecting too much out of a pair of metallic shoes? Do all metallic shoes wear like this, or did I pick a dud?
