It's good to know everyone has their experiences in Spain. Besides a lot of staring I personally haven't had a lot of trouble. But, I do want to share one experience my fiance had.

During our times there, we had shopped many times for shoes in Madrid. One time, we went to a store near the Puerta del Sol. My fiance has what some may call large feet for a woman (size 10) Although this is somewhat unheard of in Spain(I think it's a 42) she found many pair to fit her. In this store, she asked the gentleman to help her. He acted amazed that there was someone with feet like hers. I spotted a pair on the shelf that was her size and when I went to get them, he shouted "No!" We tried to explain that we found her size and he kept saying" No!" Then he finally said in English "No shoes for you!" So, we left, laughing all the way out the door.

Just thought I had to share my fondest shopping experience.
