Ahh...I always appreciate your voice of reason Stick9. CCM would not say 220 for 2 minutes if they didn't mean it. Heck, it probably can handle more than that, but they need to still be on the safe side, otherwise everyone baking their skates would wreck them.
I have baked many a skate on my own (I use a convection oven and a temp gun to make sure the temp is accurate) and I've never pushed higher than 220 on temp (oven turned off before I put the skate in), but I have left the skates in for more than 2 mins on occasion (never longer than 4) and I've never had any problems to date. I make sure to pull laces straight out, not over-crank them, and make sure the skate wearer doesn't move for 20 mins.
The OP pic looks like an over-bake and/or over tightening of laces. And yes, just cause it's a LHS, doesn't mean the employee does it right all the time. In fact, I have witnessed myself quite a few store employees (won't name the stores), that clearly pull up on the eyelets and/or tighten too hard, and I have also seen many kids of all different ages not stay still while the boot is still hot, literally flexing their ankles. (I guess some people can't help themselves)
I also agree. Use the warranty and just exchange them and then be there for the baking process. As long as you're not a serial skate returner, you shouldn't have a problem with CCM customer service.
