You just bake them at home of course! I´ve baked pretty much all of my skates at 180-190 degrees for about 6-7 minutes. Works every time.
Some occasions I have put the skates in a sauna at around 170 degrees and left them in there for 10-15 minutes. Skates got soft and pliable that way to.
I feel many players think that the skate-oven is working wonders, when it´s not. Just warming up the skates.
No need to pay 50$ for that when you can do it yourself THAT EASY.
