Replying to Shin Bruises

Hi NS, lately every-time I go skiing with my FT drop kick boots, I getting these bruises on both of my shins, and i'm not sure what to do about them.

When I get these bruises I cant ski again for about 3-5 days and the bruises don't go away, but they hurt less.

I've been considering getting the Pro Boot Liner that is supposed to be softer, or get a new tongue with a softer flex.

Any input on how to fix this would be appreciated :)
