I wore the same pair of snakeboots for the 3rd year and they are still in good shape.  The goretex is holding well, no problems with the soles, feet stay dry and great ankle support and foot/leg protection.  Remember there is a difference in snakeboot style, there a rubber ones just like muck/knee high boots, there are ones that have a zipper up the front, neither of which is what I wear.  I prefer and wear Cabelas laced, goretex/leather boots.  You can adjust and tighten the support as needed.  

I can and have swam in the snakeboots to test them out.  More importantly, I know they stand up to the wear and tear, and Cableas will replace them if they fail.   My trip partner has worn the Chotas for 3 years after trying my boots this year, he is buying a pair of snakeboots.
