I finally got some gaffers tape for exactly this purpose based on
@Noodler s recommendation here
https://www.pugski.com/threads/long...-1700-b-boot-heaters.13202/page-2#post-308202 and I have to stay, I like it MUCH better than duct tape, which leaves gooey residue everywhere and curls up on the edge. The original material they used to cover the spine hardware had come off, so I put a smooth single run of the tape from the very top of the boot to below the zeppa, so there is hopefully no edge to rub on and curl up. I’ll think about sandpaper as well.
I’ve also used gaffer tape a couple times to seal the instep boot flap to stop leaking based on
@James recommendation. It works well for this too & then comes off clean at the end of the day. I’ve found it works better to put the instep piece on first and then go across the toe box.
Re: repairing zipfits, I’ve used silicone to reattach edges of the sole to the upper and then covered that with an iron-on seam tape (low heat!) I had originally thought I would just use the seam tape to hold the repair until the silicone cured, but the tape bond was pretty strong and it’s stayed put for a few seasons now. Certainly not the nicest looking repair, but it worked for me.
Re: silicone spray. I plan to get this next. Since people have been using this for a while, I guess there aren’t any negative effects on the Zipfits? Do you wipe them down each day, how much do you use? How often? Edit: I’m also seeing “dry” and “wet” sprays. I’m guessing you use a dry spray?
@jmills115 I can’t believe they destroyed the integrity of the heel cap AND the stitching in two different places!
This is why I’m still hesitant to get boot heaters w Zipfits that I take in & out of the shell everyday (cutting the Zips, plus the potential of damaging the heater cable too!) Though it does sound like
@Noodler has had good luck with his setup.
