I was looking in one of my hockey cofee table books and I noticed Boris Mikhailov was wearing a pair of skates with three distinct diagonal white lines on them just like Adidas has on their shoes.
I'm pretty sure the book is A Pictoral History of Hockey, and it's the picture of Boris holding the 1979 Challenge Cup. Did Adidas make skates?
Yes, a lot of the European players of the 1970's-early 80's wore adidas skates. If you watch the video of the 1980 USA Olyimpic game, you will see many of their players in those skates. Kind of like Graf skates became the big thing in Euro in the 1990's.
