If shell-stretching/punching is perfect in some areas... does more heating for future punches cause the shell to lose all the punching progress that has been made? One of you guys said something about subsequent heating causing the "memory" in the plastic to negate punch jobs.
I am almost where I need to be... right boot is done... left boot needs two specific areas blown out more.
When I go back in (at my shop you need to have employees fill out a boot-fitting sheet where punches must be... in fairness to them they are busy and they're not getting any new profit from me)... anyway when I go back in do I need to request 1mm punches in all the areas already punched to maintain the good punch efforts?
Also, I am now comfortable taking a power sander to my custom footbeds... I've already trimmed down the toes... but in the 5th met tuberosity area, there is about 2mm that can come down... shall I start here or just keep going with the shell stretching?
