when bindings are mounted do they use the shell size or mondo size or what? I always give them my skis and my boots, tell them where i want the mounted and thats all I know.
The reason im asking is my current size is 28.5 (not sure of shell size) and im looking at either full tilt hot doggers or booters (leaning toward booters for the wider last) and they have different shell sizes, 28/28.5 hot doggers are 318 shell size and the booter 27-28 shell size is 315 and 28.5-29.5 is 330

they use your boot and BSL. every binding as a little bit of play, meaning you can make it a few millimeters bigger or smaller if needed

BSL is boot shell length? so that would be the 315 correct? in mm

BSL = Boot sole length and it's what you are referring to as "shell" size, its the number in mm thats printed/embossed on the side of your heel ....
the 315mm in your case is the distance from tip to heel measured over the sole of your boot, this number is used to mount bindings/calculate mounting point .....

the 318 and 315mm bsl are gonna be perfectly interchangeable, you should check on your current skis if the heelpiece can be adjusted another 15mm back to fit the 330 BSL shells....

probably not, unless your bindings are already stretched to the limit, you'lll probably be fine ...

use a sharpie to mark where your heelpiece currently is on the rail, then insert a flat screwdriver in the indicated position and use it as a lever to push the little metal tab upward, this sets the heelpiece free inside the mounted rail and allows for some adjustment back and forth...

then slide it all the way forward, remove screwdriver and give the heelpiece a little whack with your hand so you hear it "snap" into a fixed position, now the heelpiece should be all the way forward, now look where your sharpie lines are, if the line is 1cm or more forward of the line on the rail you'll be fine, otherwise you'll probably have to remount ...

now when you've done that, and you want to readjust your bindings, do exactly the same thing with the screwdriver, align the original sharpie lines , remove screwdriver and give it a little whack...

(normally seen theres also an indicator on the PX bindings that indicates when the binding is still free in the rail and when it's locked, its the little window right above the tab, if i'm not mistaking when its green it means the binding is locked into place and ready to use.....)

also, i'm not responsible if you fuck up your binding, adjusting it is done at your own risk .....

well, let's hope you don't have to remount....

if your new boot is 1cm / 10mm smaller you'll only be 5mm or 0.5cm more forward of your old mounting position
this isn't enough to make a real difference in your skis performance ....



so in your case if you want to remain around the center, you have 2 (3) options...

option 1

remount the heel and mount it a little bit more forward, (with your new boots being about 10mm shorter then the old ones you'll be riding +5mm of your current position, so +0.5cm from center )
this is slightly forward but i'm quite sure you wont even feel the difference ...

or option 2

remount the toepiece

and bump it 1cm back, with your new boots this will result in you riding at -0.5cm from center, so slightly back, but probably not noticeable, just like the +0.5

(option 3)

don't remount you'll be mounted at +0.5 with your new boots ....


(beware, for remounting option 2, the toepiece,
this -0.5 depends on how much your tech will bump it back, i assumed he'd mount 1cm back from original, if, lets say, he mounts 2 cm back from original you'll be riding at -1.5cm .....)
