We are on our third or fourth pair of these particular shoes. We only buy them when my little one has grown out of the last pair. Our most recent pair did have the bottom come halfway off of one shoe, but it was after months of hard wear and tear at daycare. Just ordered a new pair for my (almost) 3 yr old today! And she is the pickiest connoisseur of shoes you will ever meet... (the number of other adorable, yet unworn shoes in her closet it makes my bank account hurt)
Note: The version with silver top and white base is nothing like the all-silver/grey shoes. The all-silver version is SO much lighter and more flexible. Both are cute and durable though.
