If it has been 11 years since your wife has seen her podiatrist, I would highly recommend a consultation. Feet do change size and shape throughout your life. Several factors may contribute to this including weight gain, pregnancy, trauma.
A podiatrist should perform a thorough history,physical exam and gait evaluation. Then he/she can recommend the proper orthotic for her.
I hope this has been helpful for you.
