Downhill skiing is
full of all kinds of physics, its the
act of succumbing to gravity! To
transmit the actions of our bodies
into our skies, we use boots and
binding.
Many years of engineering,
bio-mechanics, and physics have gone
into the design of these
products--focusing on safety, comfort,
and performance.
