Insoles in shell fit

post #1 of 5
Thread Starter 

I appologize if this was asked previously. I have some previously made instafit insoles, when doing a shell fit do I put those in the bottom or do I do the shell fit directly on the bottom of the boot?

put your foot in the shell with toes just brushing the front of the toe box and then look in back with a flashlight and you only need 15mm of space open behind your heel to the inside back of the shell----this is measured at the longest point of your foot on the heel about 3/4 inch up from the bottom of the boot.

 

By the way a 1 foot piece of 1/2 inch "CPVC" pipe is exactly 15mm out side diameter---a good measuring tool.

 

15mm is the maximum you want to see---more might seem comfortable---- but then, what is "comfortable" about no control on a Black Diamond Steeeeep pitch run?

Honestly doesn't matter much whether you use your footbed or not as they typically won't change your foot length much if at all.  But since they may and you have some I'd put them in and measure as Mike said.

My issue has generally been the volume of the instep, not width or length although older langes were too narrow for me. Which is why i asked about the footbed which I would think would change the volume of the boot.

shell sizing is primarily a way to assess length of shell against length of foot. You can gain a little width knowledge too. Instep is a combination of  the boot roof height ( which is adjustable ) boot board height, ramp angle, thickness of tongue, etc.

 

there is no rule of thumb guide for shell sizing for the instep because of all the adjustable variables listed above. at best you can measure the heel/instep perimeter and attempt to match boots based on those dimensions. a good boot fitter has a big bag of tricks around either opening up room above the instep, or closing the boot down on top of the instep to achieve heel hold back and hold down.

 

your footbed if properly built neither raises or lowers you instep height. it should simply match the bottom shape of your foot, providing comfortable contact.

 

the one area where you may want to put your insole into the shell is to check and see that it just fits cleanly and does not conflict with the shape of the shell.
