I've read that your feet get bigger with age, especially if you're over 40 years old. I'm 74 years old and I have a big problem with buying shoes online, they are big enough. When I was younger I could wear a size 11. But lately, size 11 is too small for me. This time I bought 12 and it's still too small, about 1 size smaller, so I returned 12 and ordered 13. It is also possible that the faux leather does not stretch. Otherwise these are nice shoes.
