Haptics
How much you physically feel. Turn it up and every bump, vibration, and ache registers. Turn it down and the pain, tension, and discomfort fade into the background.
Nicolas Mermoux and the Ultra Trail Collapse
Haptics was turned up to maximum for Nicolas Mermoux as he experienced every impact and vibration through his legs during the 101-mile race. The thin-soled shoes transmitted every rock, root, and hard surface directly to his muscles and joints. His body registered each punishing step until his quads shut down completely, making him hyper-aware of the physical interface problem.
