Replying to Best ski boot for absorbing impacts

i fractured my tibia (shinbone) about a month ago now, and when i get my cast off and am ready to ski the doctor said i would be ok for jumps and rails as long as i dont case much, or take any huge impacts. i was looking for some new ski boots and heard that some of the recent freestyle ones had some technology that helped absorb a little bit of the impact, are there many of these, and are there any that are decently priced? thanks
