I dry both the shell and the liner; take the liner out of the shell, take the insole out of the liner....dry overnight on air flow diy dryer...no heat. Btw I don't lace up or tighten the boa...but I'm not obcessive. take a look at below
thanks for clarifying everything
well if i tighten boa is it bad? can my lace system will break quicker instead of those who not tighten boots while not riding...?
