Love these boots, saw this thread, couldn't resist replying. I know quite a bit about socks and footwear. I use waterproof knee-high goretex socks for walking knee deep in the snow or cold streams - keeps it warm and dry. I actually like the flexibility of a less warm liner in cochise 130: when colder, I put a warmer sock. When warmer, e.g. skiing resort in the 30's or on tough climbs in 20's I put highly breathable thin socks and my feet don't sweat as much, and stay warm enough in cochise. With intuition liners I always get sweaty feet skiing hard and fast, and sweaty leads to cold feet later, especially on the lifts or on breaks in the backcountry.
I'm used to skiing with cold sweaty feet from young age, as I'm sure most of you, so I can tolerate a full day of cold feet, but it's nice that cochise liners are not sweaty by default, and can always be made warmer by warmer socks.
Btw, I did the boot fitting with warmer socks, but when I wear a thinner sock I just clamp down more with the buckles. Micro adjustments on the buckles work great too.
I also like that cochise boots are not 100% waterproof, because waterproof = always less ventilation = more sweaty feet. I prefer the flexibility of using the boot cover in powder to waterproof when I need it. Bootcover also adds warmth of course.
Another thing that is great for this liner is it prevents toe bang on landing from jumps, because of the extra inch of space between the liner tip and the shell.
ABOUT TAKING OUT THE LINERS, RIPPING, ETC:
I took out these liners exactly 8 times to change from din to tech and back. Did it carefully with the boot horn, no damage. I don't take out any liners for any other reason - much faster and less work to use boot dryers or a hair dryer :). Years back I would just stuff em with paper towels overnight + put next to a room heater at the right distance.
Hope this helps!
