Yep, hiking kills 'em fast.
We pack in and put 'em on streamside.
Downside is you can't spot fish along the way.

I've worn out one pair of boots so far with these (Simms) waders.
That's pretty good, I think.
Probably won't buy again due to the culture change in their warranty department.

I have always used sock liners on the outside of the neoprene booties to deflect some of the wear away from the booties.
Seems to work and also makes putting the boots on a little easier.
I think that these are the ones I've got....

I'm 10.5/11 and bought the XL for over the booties.
They're tough....using same the pair since '96.
