How tight should your ankle cuff of inline speedskating boots be?

I have been using a pair of generic Powerslide XXX boots for a couple of months now but I realized I am not sure how inline speedksating boots are supposed to fit at the ankle cuff. I was wondering why getting on the outside edge was so difficult and I suspect my ankles may be too small for the boots.

The actual foot part of the boot is highly snug. I have heat molded the boot and there is little to no wiggle room with ezeefit 1mm liners (if I wear socks the boot becomes too tight)

I have taken 3 pictures of my left foot. In two of the pics I am forcing my ankle outward and inward. (right foot has a similar view)

• Standing neutral
• supinated foot (pushing my ankle outward)
• pronated foot (pushing my ankle inward)

Questions:

• Is there too much of a gap in the ankle?
• What should a correctly fitting boot feel like at the ankle? How should it feel if you push the ankle outward/inward?
• If my ankles are too small, what's the best way to "fill up" the gap or make the gap smaller?

Thank you.
