AIRCASTWalker Brace / Walking Boot Replacement Foam Liner with Insole (FP and SP Models)

I need a replacement for my below the knee boot for my right leg. It is old so I don't know the model. Cn you give me dimensions for the liner?

How do I the odor away?

Does the fp replacement liner work for the airselect model? amazon does not seem to sell a replacement liner specifically for the airselect model.

Does it come with the foam replacement that sits on top of the boot sleeve?
