i am having the exact problem in my left skate!  Apprently it's a bit loose for me at that area, so I think I could elimiate the problem with a pair of thicker socks!!  (I used to wear very thin socks, but the skate is just a bit too big for me, and that forces me to use a shockdoctor footbed to reduce the room inside the skate, and now use a slightly thicker socks to make it tigher!)  So I think if you maybe having the sample problem, you may try changing your socks!
