I purchased the gold and rust in size 8M.  This is the size I always wear.  But, they were a little big on me.  I could stick my finger in the back by my heel.  So, I called and talked to Tina who was amazing.  They exchanged for 7 1/2M with no problem.  Cute shoe.  Great padding and felt somewhat snug.  Really liked the style and colors.  Hope the smaller size still works in the summer when the feet expand some.  I couldn't walk in the 8's when my heel slips out.
