Boots for winter are like anything else,you get what you pay for.Personally,
i don't think you can get a decent pair for much less than a ton.Loads of
boots are classed as winter boots,because they're waterproof,and will keep
your feet reasonably warm whilst on the move.The real acid test is when
you're static.I have a pair of North face chilkats which do keep my feet
quite comfortable when static,and unlike moonboots,they are'nt cumbersome.
I also have some North face slot boots,which are lighter and slightly higher
up the leg than the chilkats.These also have hard little plastic type studs
on the sole,and are said to have excellent grip on snow and ice,but i've yet
to try them.You'll get little change out of a ton for either,although the kats
are slightly cheaper.Another thing is you should always wear wool socks,
preferably merino wool,and i mean pure wool,not the cheaper 'wool mix'
$hite you see advertised.They are'nt cheap,but they are the best for the
job.
If you want guaranteed warm feet,then look at what is worn in countries
that have real harsh winters,or what scientists wear at polar stations.
You'll probably find the most popular are Baffin or Sorrel.These have boots
guaranteed to keep your feet warm in temperatures as low as -70c,even
when static,but most people round here,would rather have cold feet than
pay £150-£200 for a pair of boots.There is also the chew of having to
send to the USA for the majority of them,but like i say,you get what you
pay for.
