When these first came out I was so stoked. Just was signed on with Korkers Prostaff team and the first of the new series! When they updated the boots with protected stitching around areas where the boot made contact with rocks and debris on the river floor.
My pair have been though hell and back. I have over 300-350 days on the water with them. ALL the areas with protected stitching has held up but the couple areas that didn't have it some of the stictching has failed but not to the point where the boots aren't wearable.
Comfort hasn't worn out from excessive use. They still are very comfortable to wear.
Where the sole meets the material very little to no wear on the boot, I've heard of premature wear and the sole separating from the material I believe it's from how you wade if you constantly shuffle your feet in fast water constantly rubbing your boots against rocks I can see them wearing out very fast.
Overall I give these boots a 10/10. I've literally tried to break them and gave up within a year that I had them. Worth 200 bucks over other brands that are way over 300-400 bucks for less features and functionality.
PS the new Wraptor boot is mind blowing. ZERO STITCHING the material is one piece and I believe will solve most of the issues wading boots fail on the water today and this is an industry first from Korkers. They release in December 2017.
