adam… the big flaw with gore tex boots is that they take forever to dry and theres one big honking hole, through the top … sure you have gaiters, but stuff happens … that incident a few years ago where a climber i saw step into a creek was wearing croc gaiters, enough water somehow got over the gaiter to soak his leather boot through
with removable liners, at night you wring em out, take em into yr bag with a hawt nalgene, and get them less damp and warm … if they are simply a bit damp fro sweat, you can actually dry em out
im not sure about yr area, but around here some guiding services will not accept clients on multiday trips in winter should they not have boots with removable liners … for shorter trips you can likely get away with single leather boots, etc …
if you have ever had soaked boots in winter, youll know how long they take to dry even indoors, which is why they make "boot dryers"
its up to you what you use, just have yr footwear nailed down … as thats one thing that cant go wrong
edit …
heres the info from the ADK winter school that someone earlier posted … decide accordingly …
A: Our requirements for boots are strict and non-negotiable. In the Adirondacks we may very well have to contend with rain and slushy snow, followed by rapid and drastic drops in temperature. We get many, many questions every year regarding the suitability of various boots for our program. In order to address these We've come up with the following general guidelines – The Winter Mountaineering School Commandments of Footgear. Please read carefully and fully.
No boot, no matter what the manufacturer's claims, is waterproof when it comes to the varying conditions in the Adirondacks. Frozen boots = frozen feet. Therefore for overnight backpacking sections, removable boot liners are mandatory, no exceptions. Removable liners allow boots to be field dried at best and kept from freezing solid at worst. Also, do not confuse a removable midsole for a removable liner.
VBL sock liners (see below for details) are strongly recommended for all sections and are required for over night backpacking sections. They can be difficult to find. In a pinch, a pair of bread loaf bags (2-per foot, per day) will work. Many of us with years of experience have come to realize that even the best of VBLs eventually delaminate and leak so many of us use both the VBL and the bread bags, or two bread bags together. They are worn between your inner and outer socks. They work. Trust us.
There has been a great proliferation in "high tech" winter foot gear. Many manufacturers are making boots similar to the Columbia Buggaboots. In general they are one-piece construction and lack removable liners. This type of boot is now considered acceptable for our weekend day hiking section only since they can be kept warm overnight and dried while staying at the Loj. In general these should have full lacing, heavy lug type soles, full rubber waterproof lowers and may have synthetic or heavily factory water proofed leather uppers. They must also work with your crampons, gators, and snowshoes. When in doubt ask.
GI issue mouse boots, i.e. the big white ones that make you look like Mickey Mouse, are still acceptable for our purposes for overnight trips. They are tricky to get to work with most crampons, snow shoes and gators however so try them out first. Many miles were logged with them in the early years of winter school. Or you can use…
Sorel type pack boots. But they must satisfy the fist commandment above and have removable liners. They should have full lacing or an appropriately adjustable closure system, heavy rubber lowers with a lug sole, and synthetic or heavily factory waterproofed leather uppers. But most instructors now use….
Plastic Mountaineering Boots. These are the most appropriate footgear for our school. They have some drawbacks, not least of which is their cost but overall they work the best for our overnight backpacking sections. They are a bit tricky to fit with crampons, snowshoes, and gators so be sure to check out the fit of this gear before arriving at school. They can be rented at some gear shops, such as EMS in Albany and Lake Placid, and The Mountaineer in Keene Valley.
There are, in addition to the boots mentioned here so far, some very sophisticated, very expensive, single leather mountaineering boots available on the market these days. These boots are made for fast, alpine style ascents up mixed routes and are really made for conditions and terrain we do not have much of in the Northeast. Most importantly these boots do not satisfy the first commandment above and so, despite their expensive pedigrees, are not acceptable for our overnight backpacking sections.
