This thread is so important in relation to baying boots, that i post a link:https://www.newschoolers.com/ns/forums/readthread/thread_id/679030/

Just
thought I'd chuck this in here because I see quite a lot of threads about
people with foot pain and when people suggest footbeds they're like "yeah,
maybe I'll try some".
Pretty much everybody should get footbeds.
The reason for this is that most boots
don't actually come with a proper insole. From my experience the higher-end the
boot, the less of an insole it will come with. For those of you skiing decent
boots without footbeds, go pull the insole out. I bet it's a flat piece of
cardboardy fabric about 3mm thick. The manufacturers just chuck them in there
so you have something to try the boot on with (if you don't take your footbeds
to fittings). I guess they assume you'll get/have a proper insole anyway, if
you're buying expensive boots.
The ones that come in the boots provide nil
support for your arches so when you're putting pressure on your foot it becomes
flatter, longer and wider. This is why your foot feels squashed from the
sides or on the toes when you ski despite the fact that it felt great in
the shop.
Likewise they have almost no heel cup so your
foot can slop around in the back of the boot, reducing control and energy
transfer.
In my opinion a good footbed is one of the best
investments in your equipment you can make. You'll ski better and in more
comfort. You may get away with some $10 replacement insoles from a shoe store
but really you should be spending the money and getting a pair of custom molded
ones. The difference is just unreal.
Footbeds are
a bit of a dark art in bootfitting. The thorey for footbeds comes from podietry
and this is not somthing your average ski bum boot fitter knows much about. It
takes years to learn and is pretty complex. Because of this your proberbly
going to be best looking for an experienced boot fitter with at least 5+ years
making custom footbeds.

So I wanted to answer some
common questions about footbeds.
What do Footbeds do?
Footbeds help support the
arches of the foot, keeping the foot in a neutral postion and helps with impact
cushioning. But what does any of that mean. Well lets start with your feet. An
interesting thing I once heard about feet is, every day each foot takes
1,000,000lbs of force just from walking around. With that sort of force every
single day, our feet need to be able to cushion impact effeicently. This is
what the arches do. They act like suspesion for the foot. But if these arches
are left unsurported, they some begin to strech with that much force every day.
This is when feet begin to flaten and pronate.
A good footbed will suport the
arches of the foot, and help them cope with the great forces involved with
skiing. If your foot is unsurpoted, it can feel like your foot streches
underneath, and this can cause cramp. The foot will genrally get longer
underforce, which could push the twos into the front of the boot.
So if you park ski, a footbed
will help support your foot when landing.
What is a neutral postion?
Its best to think of your
boots when thinking about this. Boots flex in a fowards motion but not at all
side to side. This means for your foot and leg to fit the best they have to
match this, ie straight.
When your arches begin to drop
or flaten genrally what happens is your foot begins to lean to the inside. This
can make your foot apear wider then it actually is. This is called a pronated
stance. A neutral stance is simply when the leg is straight. A footbed helps
acheive this by suporting your arches to help the foot maintain this neutral
stance.
What footbed should I get?
Really the only person who can
answer this is someone asses your feet and stance. Unfortunatly this means
Bootfitter.
What are the differnces
between footbeds?
There are 3 main types of
footbeds, below I will list the 3 and the pros and cons:
Trim To Fit
These are your most basic
footbeds. They have a predifined shape, and are designed to go stright into
boots.
Pros:
Cheap
Easily available
Cons:
Not custom to your foot
Limited selection of shapes
Trim to fits should be thought
of as a minimum. They will be better then the stock insole but thats about it.
You will always be better off with a full custom footbed.
Example Brands:
Superfeet, Sidas, Sole
Custom Trim To fit
With these footbeds, a computer
scans the pressures on the base of your foot, and selects a footbed shpae which
best matches you from a data base. This shape is then sent to a milling
machine, and a footbed is produced.
Pros:
Better the Trim to fits
Easily replacable. Your foot
is kept on record so a new footbed can easily be made.
Cons:
Expensive
Often very firm
Still not totally custom.
These footbeds are great for
carving. They support the mid tarsel joint (back of the foot) very well, but
not so much the front of the medial arch. This means in practice they have less
impact protection compared to other custom options.
Example Brands
Surefoot
Full Custom
These will be your best
options. They are usally cheaper the custom Trim to fits but more then standard
trim to fits. There are also 2 types Weighted and Unweighted. The differnce is
in teh production preocess. For weighted footbeds the footbed is produced when
you are standing up. Unweighted are made when sat with no weight on the foot.
In my opion weighted are better, you stand when skiing so its better to make
the footbed standing, rather then sitting.
Pros:
Fully Custom
Totally customisiable,
different flexes, different volumes, custom heel lifts, canting. Pretty much
anything you need.
Foot can be postioned for
optimal fit
Cons:
More expensive then trim to
fits
Need an experienced boot
fitter to make them.
Overall if you can get a good
weighted custom footbed, this will be your best bet. Get them when you get the
boots fitted, it will give you the best fit from day one.
Example Brands:
Sidas, Aline, Superfeet (avoid
the superfeet korks if you can)
So thats about it for now, im
sure i have missed out allot of things but hopefully this sheds some light on
footbeds.
