I'm guessing the most fragile part of the Softstep would be the little plastic inset bit that carries the display and jacks. Haven't tried to break it, but it seems a little wimpy at that point. The rest is pretty unbreakable from what I've seen and cause that's how it's marketed!
I would also make sure that part, with cables plugged in, should be kept safe from errant stomping feet.Right angle usb cables are available -- less tempting to a toe or HEEL.(The BBcode don't work, no bolding or itals, so CAPS)
Wrapping it in a towel and/or snugging it in a laptop bag big enough( you're carrying a laptop yeah?)should more than protect it. It's a "foot pedal" meant for stompin' after all.
Edit: Geez, I forgot the promo shot! You can put on some high heels and carry it in the back pocket of yer jeans !
