I have to give Kudos to Patagonia for their excellent customer service (again). Previously they sent me a new pair of waders after my Watermaster II waders were deemed terminal. That was great and unexpected.
I recently had a seam blowout on my rubber soled Riverwalker Boots. I called them and they had me send them in. These boots were 2009 Model boots, but I didn't purchase or wear them until 2012 or thereabouts. They probably had 30-40 days on them and I didn't much care for the sticky rubber soles--they wear fast and they aren't sticky enough when it comes to wading on granite rocks. I did many a fish dance while wearing them.
Anyway, Patagonia deemed these terminal as well. While they didn't replace the boots, they totally refunded what was paid for them with an e-card which I'll use to buy some felt sole boots. That's what keeps us buying Patagonia items.
