But I totally invented this! I called it Urban Glide, and yes, I did envision long ski-like skates to be worn, but come on! Same basic idea! Ugh, Nordic Walking! Why didn't I think to use Nordic? Everything sounds more official with "Nordic" in front of it.
Honestly though, I've had this idea since college. Because Syracuse is so effing cold, I used to try to get from point A to point B as fast as possible. My eye froze shut once on a walk to class. I'm not kidding. But, as you might imagine, running everywhere was hard to play-off.
-Why were you sprinting around like an idiot on the quad today?
-What? That wasn't me.
I found that if I held on to the excess material hanging from my backpack straps, I could use those as pole-type devices, swinging my arms as I walked, and thus increasing my normal walking speed. I wasn't running, I was gliding. Add in a nice layer of ice and I could literally slide from class to class. In the spring I always thought to myself, OK, some sort of skate should be involved here. And then I did nothing about it.
And now, years later, someone has stolen my idea about swinging your arms as you walk, and has thought to use actual poles instead of backpack straps, but same basic principle really, except that the poles have technology, design, and a trade association on their side, and mine were straps of nylon connected to a book bag. Whatever. I thought of it first.
