Over the last 10 years I bought 5 pairs. The first 2 lasted 2.5 years each. Literally put thousands of miles on them. But after wearing holes in the foam foot bed I switched to the leather foot bed. I've had them for 5 years. Wear them daily, year round. I abuse them too. Wear them ocean fishing, take them to the beach, rinse them in salt water. They're built like a tank. They realistically have another 5-10 years left in them. Which is more than I can say for any shoe or boot I've ever bought. And they're comfortable on top of all that.
