Rothy Shoe Sizing According to an Associate
"I was advised by an associate to go to larger size in this shoe. The result was a disaster! I had to wait for a backorder to become available and then the shoe was so large in fit! Now I must return the shoes and wait for another backorder to be filled, along with the return of a refund! If I did not love the particular shoe so much the process would have been much simpler!"
