Hi, I have recently upgraded my boots to a set of new 2014 vapors, they come with heat molding inserts (intuition brand), my question is seeings how I got them online, they have not been heated. Can I do this at home? If so how would I go about it? The limited info I have so far is to heat them to 120C then put my feet in them while warm. Any help would be appreciated. Thanks in advance!
