I watched it previously but since
@Noodler is the guru thought I would ask him before adding any
I learned from the official ZipFit videos, pictures of the bladders (posted elsewhere on the site), dissecting a pair of old liners, and doing a bunch of it myself over the years.
A few tips:
- Measure your feet and legs to determine if they take up similar or different volumes. Due to my accident, my right foot/leg is significantly larger in circumference/spread than my left. So the right liner is going to have less cork in it (unless the shell has already been blown out for the size difference).
- Weigh your liners before adding more cork. Knowing the liner weights will help you assess how much cork you've added to the bladders.
- Mark the plunger with hash marks to provide guidance as to how much cork has been pushed out of the tube into the liner. The hash marks will help you keep track of the plunger depth.
- Warm one full tube of cork for 60 seconds on high in a microwave to soften it before dispensing.
- Hand massaging the cork after it has been added will improve the distribution of the cork to where you need it.
You almost never need to add cork to the ankle bladders unless you have really skinny ankles in a shell that provides a "comfort" fit. If you need more heel hold down power then usually you will add more cork to the tongue.
Note that over the years the entry points have changed a bit in the different models. Most models have a tab that is pulled apart to "expose" the opening for the tube. Pulling the tabs apart can be challenging the first time. There were model years where the tongue did not have separate tabs that you pull apart and instead had a single tab that is pulled forward away from the tongue while the tube is slipped in between.
