Shoelace Hurdles

I spotted a giant red sneaker parked right in the middle of the hallway and decided it was race time! I sprinted across the floorboards, leaped onto the thick rubber toe, and scrambled up the laces. Halfway up, a loose blue shoelace swung loose like a moving obstacle. I dropped low into a sliding duck, slipped clean underneath, and popped right back up onto the woven mat with a triumphant hop! Every single hallway can be an obstacle course if you run fast enough.
