The spurs are a sound effect. I spent about 30 minutes in a Hobby Lobby ringing all the different sizes of jingle bells. I found one that is about a half inch or so wide and thought it sounded nice with others. So I put three in each of my big shin tool pockets. It's subtle, but a few people have asked me about it. I did it more for myself than others, but in a quiet venue, you can definitely hear it.
