Replying to Wooden wedge for rampages

sooo my ankles just arent working well with my rampages. I got them last year and skied them about 25 times. during the summer i hurt my ankles and i now i have bigger constantly swollen ankles. so i was talking to my dad and he suggested that i wedge a piece of wood (where my ankles fit in the boot) and then proceed to heat the boot with a heat gun until the actually shell of the boot expands. what do you guys think of this? have any of you tried this before? thanks
