Well its not Red Dog Hockey boost from what I can tell. If it was it would probably not all be the same on both players on both skates. Looks to me like issue with hitting the boot so they raised the it by shims. No other real purpose if both players are exactly the same.
I don't want to derail but to me, that is my favorite era of hockey equipment. Looks like Bauer 1000s, CCM HT2, and those Ferland's would have been on my dream list when I was in my teens.
