I'm on day 9, tomorrow will be 10 with my new SPKs, should they be done packing out by now? I haven't really noticed any change in how they fit since day one so I'm just checking.
10 days of hard skiing should definitely pack the liners out well..
Thats based on normal ski boots actually being used for normal skiing/carving etc though, in which you would exert MUCH more pressure on the liners, so I guess its a bit different for a park boot.
I disagree. In my experience the change is so subtle that you won't notice it until the end of a full season, but you will definitely feel a change then.
