If your shoe size have decreased nearby are three things I can think of are freight loss, but you stated you didn't lose, water retention, or osteoporosis and drastic bone loss..I would jump to the doctor and get tested for this.

It can be when you were within 9.5, you were wearing a somewhat over sized shoes, but when you are in 7.5 today, it may be the shoe making was slightly different within their sizing standard and you are in a under sized shoes not because your foot were going to the rear.

The reason I own this thoughts,is because it is unlikely feet can shrink. Bone growth does not use that rule.
