These are very comfortable shoes and I had another pair of these that I finally wore out after about 2 years. I ordered the same size I had originally and they're too small. I've noticed that with a lot of shoes recently however. I use to wear a 9.5 to 10 and now I'm up to 11. I'm old and my feet are no longer growing, so I'm not sure what the sizing problem is with the shoes lately.
