Thread: MY boots squeak !

I have the very annoying ( now ) problem Of one boot ( left ) squeaking .
I have....
Washed / dried and cleaned them .
Put dubbin on them
changed the insoles
Shock talc into them
Sprayed silicon into them
pryed the sole where its possible and jammed contact glue in there and clamped the boot in the press

Nothing seems to work .
So, heres the questions
why do boots even squeak in the first place , and when they do, what are the reasons ?
the boots have had only 3 roars and weren,t cheap . Keen brand "Keen dry " water proof
cheers
