This product works great for mending shoes, and boy do they give you a HUGE bottle of this stuff!  I was shocked when I received the package and a jumbo toothpaste sized tube came out!  I used this to mend a tear in my synthetic material gym shoes.  There was a rip in the fabric where I snagged it with a screw.  I applied a VERY small amount to the effected area and let them sit for 2 days (better safe than sorry).  They have been going strong for a month now and don't look as if they're going to bust open any time soon.  It dries clear.

Great product - I probably won't ever need to buy it again though because of the generous amount you get!
