While I still maintain that I probably don't need them (a thick pair of socks can do the same job), as they are definitely only for more casual days, I own them now, have had plenty of wear out of them, and can see them being useful for the rest of their life span.
I have in fact worn them enough that last year I had to get them resoled (the rubber was worn away so much it was letting water in) and in the last 2 weeks the stitching has started to come loose, so the body of the boot is separating from the sole. So I have left them in again.
It can be frustrating paying for repairs, the resoling cost €40, but we need to change our mindset about the value of what we own, and stop comparing with the cost of buying cheap stuff new. Sure I could have bought a Penneys version for less, but if I was buying and throwing out a pair every year that is a lot of material, labour and waste.
I can´t win the argument for repairs based on cost to you. So it is just a case of thinking about where you shoes came from, where they are going to end up eventually, and how you treat them while you have them. Keeping them in good condition so they last as long as possible and then disposing of them responsibly is the best we can do.
