ski camping you are in ski boots all day and you need to
put on your insulating layer after the day ski. Whatever
the footwear is, it is at outside temperature and your foot
has to warm it up before it can insulate you from the cold.
CCS mukluks are able to warm to your foot temperature quickly
and able to insulate the foot quickly because of their extremely
light weight. (It always will require more energy to warm
more weight regardless of insulating values.) CCS mukluks
are made to be able to be worn over cross country ski boots
or running shoes, (CCS recommends a simple cloth bag to
slip over the shoe before inserting it into the mukluk.
This makes it much easier to get the shoe in and out of
the mukluk as well as provide a vapor barrier, and a wear
layer.) The upper inner and outer layers use supplex nylon
on the uppers with coated Cordura nylon lowers.
lacing system is quick and adjustable with 2 cord locks
on the main lace. The foot can be tighter than the calf
section this way. A separate top draw cord and cord lock
keep out snow if you post hole over the top.
