This is what i mean: http://www.skimo.at/skibergsteigen/files/2015/02/ISPO2015-_-La-Sportiva-Syborg-3-_-Bild-Karl-Posch.jpg What is a strong type of glue for this (marine epoxy)? And what type of fabric too (goretex?) I also have a cuff mod with holes on the side i want to cover up with fabric too.

I recommend polyurethane construction adhesive. Sand plastic surface with 320 grit and remove all dust. http://www.homedepot.com/p/Loctite-PL-Premium-10-fl-oz-Polyurethane-Construction-Adhesive-1390595/202020473 It is flexible and lasts for a very long time. Comes in several colors. You really want to wear gloves and tape off all of your boot where you don’t want it to be stuck. It will stay on your fingers for a week. I have some construction clothes and work boot soles that it has been on for more than a decade. In the video from Perre Gignoux they appear to use regular super glue to join fabric to carbon, but carbon is more rigid and accepts glue much better than flexible plastic, so I don’t think it is the way to go. I was thinking when I do something like this I would use the polyurethane adhesive and after that I would drill holes in the plastic boot lower with a 1/32 dremel bit and stitch fabric on also with heavy nylon thread. But this was for adding a thick snowboard upper to a pebax lower, maybe heavier material than what you are thinking. I don’t think you need to stitch with just one layer of fabric that isn’t taking a lot of load. https://www.amazon.com/Dremel-660-Drill-Bits-Pack/dp/B0006O8S0O Goretex is usually just a membrane added to nylon fabric. I’d find the heavier weight gore coated fabric or just use some Cordura fabric with a urethane coating which is easy to find.

It looks like for most of those fabric tongue replacements, there are some additional rivets here and there for extra security. Maybe you can try that instead of the stitching. I don’t get how those full carbon boots account for different foot shapes. You can’t do any shell punching, I’m assuming, on carbon. Guess you just have to reply on the liner to mold to your foot. Kind of limiting. October 19, 2016 at 8:06 pm #795590 Scooby2 611 Posts Yeah, I think they just deal with the pain. The high end racers probably have the shells made around custom molds of their feet. Viewing 4 posts - 1 through 4 (of 4 total) You must be logged in to reply to this topic.
