Curious in the midst of this discussion if anyone has ever tried these...and what their experience(s) were with them?   (You need to Login or Register

Haven't tried them, but my personal experience with Velcro straps in portage type situations hasn't been good.
Mud/debris can make weaken the Velcro seal, and I'd worry about the boots side zippers for the same reason?
If you were doing just short mostly rocky jumps along a river, I'd say they'd be fine.
A long muddy slog in canoe country might be another thing altogether. :-/

You could probably deal with the Velcro instep strap getting clogged, but a damaged boot zipper could render them unusable.
