New padding for boots to make them smaller.

yes, any good bootfitter will have the ability to snug up certain parts of the boot

cool. anybody know a good bootfitter in salt lake city?

any good bootfitter will tell you thats a lousy option.

agreed!

adding padding to snug up a boot is a bad idea. all that will happen is you will develop pressure points and them later on the padding will pack out forcing you to pay for it again. btw, this option is not cheap. the last time i did it for a customer, it ended up being well over $100.

thats why i said CERTAIN areas. you can easily snug up the heel, and use shims in the tongue to bring the heel back. it all depends on how big they are, and where they feel particularly loose

Your bindings might be able to be adjusted for a 1 size difference, so you could get new boots and just move the heel forward. Take them to a shop and see what's what.

Keep in mind 1 size down = 1cm smaller boot sole length (in same brand) (with the exception in of the Lange Exclusive series in a 24 and 24.5).  There are many bindings out there that can adjust to accommodate this.
Also padding certain areas like the heel and the shin, do not make a boot smaller, they are mainly used in realigning the leg in the boot. Heel lifts can be used if the ankle area has too much height, but it really does not make the boot smaller. your foot is still going to have too much room around the foot. Goes the same for L and C pads around the heel bone.
As rob said, adding padding to make a boot fit smaller is not very effective, usually ends up being pretty painful, and takes a long time and is thus very expensive.
