Hey guys,
Sorry for the late comer reply, but I think I’ve found a solution. The amount of people that are considering fashioning their own boots because there isn’t a great alternative is astronomical! I don’t know why someone hasn’t created cheap, durable and waterproof waders. Anyways, the solution I’m using for my next trail is using Tyvek overboots (usually used in the medical profession) that are relatively inexpensive (a few pounds), and using waterproof adhesive to attach a Velcro strap to secure around the top. Again, these are relatively cheap. I hope this helps, as this would solve the issue.. meaning that you would have a lightweight, cheap and durable pair of waders for river crossings
With thanks,
Elliot
