I have, er, had, a beautiful pair of Blundstone chisel toes that were perfect for fall riding: comfy, light weight (lighter than the ones the OP linked to), waterproof... great boots. got them out of storage the other day only to find that a rodent had made a meal of the heal on one and a chunk of soul on the other. I'm absolutely crushed (at least as much as I can be over clothing. :shrug: ).
I'll either resort to my
Company Boot from 5.11. It's about the same weight, comfort, water resistance as the Blundstone the OP linked to.
Here's another to consider:
Company Boot 2.0. Looks good.
