dont know much about boots besides bsl, flex patterns and basic stuff like that, but ive had my spk's for a few years now and they're starting to kill my feet just them around my ankles were those rivits are, i figure the liningsare just worn out for using them a descent amount maybe around 120 days or so, can i replace just the boot lining so i dont have to get a whole new pair, or am i out of luck/does salomon make liners specificly for the spk/wheres the best place to pick some up if possiable....any help would save my ankles thanks
