Is it also better than E6000? I need to buy some more now since
the ortho boot and also my MTB shoes are coming apart and if
Gorilla Glue is better than E6000 I'd buy that instead. In my
case it has to work for very flexible joints (sneakers, sports
shoes, not rigid cleats stuff).

I've been using a glue that is no longer easily available called
Awesome Goo. I found this on Amazon, which is probably old stock
(at least 8 years old).

Notice the photos of the shoe repairs on the left. I've been doing
something similar with good results. Here's my rather sloppy
microphone cable repair:

I think it's a urethane based goo, similar to Gorilla Glue.


Let's call that "free-form art" :-)


When I ran out of Awesome Goo, I switched to hot melt glue:

It worked tolerably well, but not as well as Awesome Goo. Those
are Wolverine Cirrus 6" aluminum toe work boots, which I wear
daily.


My experience with hot-melt glues of various kinds is generally
quite bad.


E6000 and Chinese clones are single part epoxy dissolved in some
kind of solvent. It used to be tetrachloroethylene (PERC) and
polymerized styrene butadiene (SBR) rubber. I don't know what's
being used in place of the PERC VoC which is banned in
California. The original E6000 is by Eclectic Products, which
makes many formulations and variation, all with basically the
same name for optimum confusion:

Notice the section on solvents that will dissolve E6000, and that it
really does take 24 hrs to cure.

About 6 months ago, I bought an assortment of E6000, B6000,
B7000, F6000, on eBay in small tubes to see how well or badly
they worked for various projects. In general, I verified most of
the assertions found in this article.

Except for B7000, they're mostly identical. I ended up stocking up on
the original in small tubes:

I haven't tried them on shoes or shoe soles.


I read up on it some more and found that E6000 supposedly beats
Gorilla Glue when it comes to remaining very flexible. Most of my
shoes break in the front on on teh sides and they do not have rigid
soles like some cycling shoes do. So the glued joint will flex with
every step and I walk at least 2-3mi per day aside from cycling.


The E6000 is well reviewed. I've used a product called GFlex
https://www.westsystem.com/specialty...poxy-adhesive/
-- a two part epoxy that I originally purchased to fix my son's GS
skis which had a tendency to delaminate. I needed something strong
and flexible. It's probably a little over-the-top for shoe repair,
but it works well.


Two-part epoxies are usually best. They also have a lower chance of
drying out, gumming up or becoming compromised otherwise. Thanks for the
hint.
