Probably an odd question, however I just got new skates that are identical to my old ones and I need to break the new ones in. I'm having trouble with my Right boot and need to go back to my fitter to get it punched out but it's going to be a few weeks. In the interim my old Left boot looks like it could be broken down so I'm wondering if I could wear the old Right skate (which is still good) and new Left skate. The only differences being that one blade is new and the other is several years old and one boot is stiffer than the other.
