I wear a size 6 shoe. Tried and true. The shoes I ordered from Dreamify had a non adjustable ankle strap that is too big and the back where your heel sits is at least an inch too big. Requested to return and received instructions to return to China via many hoops to jump through and at my cost. Do not buy from this company. What is scary is that they have our Credit Card Info! Sending returns to China is an Unacceptable return policy. User's recommendation: Do Not Buy from this Company.
