These are booties from a while ago.  They’ve been lightly used (fewer than 10 weekend snow camping trips).   They’ve kept my toes warm doing camp chores down to about 10F.  At 10-11 ounces for the pair they won’t compete with my new goosefeet  on weight (about 5oz for this size if you include 100% overstuff and overboots) … but then goosefeet cannot compete with my price

The sole insulation is 3/8″ CCF and the rest about an inch thick down.

Coated nylon bottoms and about 1.5″ up the sides let them get by without overboots unless it is raining or you are in sloppy snow.

Size XL … my size 12 feet fit, previous owner’s size 13’s did not
