Our CCM rep set up a test skate session for dealers a few weeks ago with a scrimmage game. I was able to bake my size and sharpen to my hollow 2 days before the event. After skating on Supreme NXG for a long time, I was more than pleasantly surprised with the comfort and quick adaptability to this skate in a 60 minute session. Stiff? Too stiff ? Depends how you lace them for me. Compared to NXG stiffness the boot was strong without being overpowering. I'll let JR carry on with his thoughts. Mine are that I would have no hesitancy moving out of Supreme into the Super Tack.
