Replying to Yet another shin bang thread

So I've had a pair of Salmon Questmax 100 (beginning to think they're too stiff) 2013/2014 for a year now and have had next to no problems. In the last couple of months I have upped my freestyle game and have started to experience terrible shin and calf bang.

So far we have tried the following:

Booster strap fitted and done up on the inside of the shell

Added foam all around the liner to reduce the volume (guilty of having chicken legs)

Already have footbeds


The boots are okay for the first day but then after a couple of runs into my second day it becomes painful to even stand still in the boots as i get a shooting pain running up the outsides of my shin/calf.

Thanks
