I've heard these mentioned a few times this year. One time at Tongyeong (i think) where Peter Robertson dropped his 'running sticks' in the beginning of the run, and then something again at the World Championships where they said 'you don't use running sticks anymore' or something along those lines.

What are they?


A picture for reference (i'm not sure if these are the same things that Robbo was talking about):
