I have a 2 year old pair of boots (Lowa Timoks) that are mostly leather uppers but with some synthetic fabric on the tongue area and between the laces. They have gore-tex in them, but the membrane is definitely failing me. The leather parts are fine, I can wax them and keep water out, but the synthetic fabric part lets in water very quickly. It's a shame, because they are nicely made boots that would otherwise have lots of life left in them, but even hiking through a short section of dew soaked brush will get my feet very wet.
My question is: Is there any product I can apply on the synthetic fabric on the outside of the boot to keep water out? At this point I don't care about trying to keep breathability, the gore-tex is toast. I just wondered if there was any way I could keep those small synthetic sections waterproof, even if it is something I have to keep reapplying.
