Here's what I ended up doing.
I sewed it up and then coated the threads, seam, and surrounding area with a seam seal (it's a vinyl glue I think, used for tent repairs and such). I covered that with a piece of red (my coat is red) ripstop tape. Everything is drying now and should be dry by morning. The back of the tube says to let it dry overnight.
Once I'm sure that it'll work out, I have another idea (thanks to Randy Salzman who got it from Scott Ferrell - gotta give credit where due) for an easier release for Intec heals. If that works out, I'll post the items needed, procedure, and pics. Early testing is quite good.
Thanks for the suggestions folks! It's handy having an REI nearby to pick up stuff like this.
