Skate size designations

[Hockeydog 8]

I have a simple question that I know someone here can answer.

When I look inside my skate I see a c/aa. I'm sure C = width but what is the aa? Are those for widths at different points of the skate. The skate in question is my One90 pro stock skates.

No rats or other objects were found in the skate

I am not !! just kidding, Thanks JR. Is aa smaller or bigger than just a?

AA is narrower than the standard A heel

No wonder they fit like they do ( a good fit) !! Thanks.
