Waterproof ?
Only if you keep them clean and do the Dubbin or Nikwax treatment regularly i.e. after every trial .
These are competition trials boots , excellent value and modelled on the Gearne & Alpinestars "No-stop" , which are better but a lot more expensive .
Gore-tex lining in a trials boot would be excessive and unlikely to last the flexing and hammer that trials riders dish out .
However , if you do use Nikwax you will be able to stand in a small river for ages whilst you try to save your bike from being washed away , following yet another failed attempt to clean the damn section !
I have no knowledge of the Enduro boot - but would think it unlikely to have a gore-tex lining .
All the best ,
Jim .
