Good Night Navy Leather Block Heel Pump

A good looking shoe but not very comfortable. I am hoping to return them as they are a bit painful to wear.

Ordered a 6C based on the fit kit; shoe slipped off my heels, so possibly a 5.5 would work but leery based on the fit kit results. Disappointed that I could not get a refund, only store credit, so be aware that if on sale you may not get a refund.
