Just got back from an 8 day trip and wore my Ecco Track II boots the whole time.  They offer great (really great) traction on the wet rocks and boulders, and in the mud (yes, it rained 4 of the 8 days I was there) and are extremely comfortable.  Highly recommend them but they are a bit pricey (around $225).  But, the Ecco company totally backs up their product.  I bought a pair 10 years ago and just this year the special rubber sole broke down.  Way out of warranty but Ecco replaced them for free anyway.
