Calgary's goalies even got in on the fun by wearing mismatched pads for practice at the Scotiabank Saddledome. The rest of the Flames commemorated the occasion with clashing attire for the duration of practice.
Rock Your Socks Day is a campaign that "shows all types, shapes, sizes of the same thing can be unique in their own way, and yet do the same thing." It also aims to create a conversation about diversity, uniqueness, inclusion and acceptance. Flames coach Darryl Sutter, whose son Chris has Down syndrome, applauded his players and the NHL's support.
"I think that's not just our guys. I think the National Hockey League and pro sports in general have jumped on board with a lot of different groups such as Down syndrome," Sutter said. "Obviously it's close to my heart. It's awesome. It just tells you about hockey players, what kind of hearts they have and the kinds of things they do quietly for special needs."
