S-astico low cut w sneakers - peach whip

The shoe fits like a size 4, I thought it’s because it’s still new I wore it twice it’s still not open. Now I can’t even wear it because it’s hurting me, I can’t walk lol ng distance.

The wrong size was delivered and I was unable to repurchase as my size was sold out. This has happened previously too! Maybe try employing people who are able to differentiate between EU size to S.A
