In skeleton, the rider starts running with the sled at the top of the track and belly flops on to the sled.
Since this is the case, how does a skeleton athlete sprint at the top of the track without slipping? The top of the track contains ice like the rest of the track, but skeleton athletes can sprint as if the ice is not an issue. Does this have to do with footwear or the ice profile at the top of the track not being prone to slipping?
