This is a hIgh resolution 3d scan of military issue extreme cold weather boots. Here are the specs:
EXTREME COLD WEATHER BOOT (ECWB) [NSN series 8430-00-655-5535]
The Extreme Cold Weather boot (ECWB) is constructed with insulation consisting of three layers of needle punched polyester foam hermetically sealed within an outer and inner layer of rubber. The boot is provided with a pressure release valve to adjust internal air pressure in the boot during high altitude operations.
When the temperature is 14°F to -60°F, ECWB boots should be worn.
I have not made the effort to decimate or texture the product instead leaving it to the end user in an effort to reduce cost.
If you like this I have other similar models available here on Turbosquid. Just insert KlipschForte in the search field & hit return.
