Dear Shoe Lady,
My foot measures 3 1/16 across. I usually wear 7.5-8 in ladies shoes. What is my foot width? Is it AA or A? This matters a great deal as AA is often pinching and B is swimming on my foot. Please help!
Even though there should be a size between AA and B (A is essentially the same as AA or 2A), there currently isn’t. You are on the right track by testing out what works for you. In the meantime if a shoe is too small and the result is discomfort, I suggest getting the next width up. I would also take into account if there is any extra padding available in order to compensate for the bit of extra space in the shoe.
Here is a lovely shoe that could work for you.
