So glad to see this thread
For nearly my entire adult life (I'm 40) I have been going to shoe stores, getting my feet measured, and being told that my feet are size 9 E. So that is what they've always sold me.
A couple of years ago I read an article about Allen Edmonds, one of the last shoe companies that still makes shoes in the USA. I thought that is a good thing, so I went to their store on Madison Ave. The salesman measured my feet. He tells me to my shock that I am a size 7 1/2 EEE! He explains to me that most shoe stores don't stock EEE shoes so the salesman have just been putting me in size 9's because that's what they have plenty off and they can make a quick sale and not have to order extra wide shoes for me.
No wonder I have been tripping over my feet my whole life: I was wearing shoes that were way too long for me!
So now I get all my shoes from Allen Edmonds. Good quality shoes, lots of styles, a decent price, and honest salesman!!
