I sent my 2 year old ESCs in to get resoled and refurbed right before the 4th and just got a confirmation email saying they were received and that it would be 4-6 weeks. The cost was $125. Will report back on the results.
I probably had 1500ish miles on these. There was still some tread on the sole, which is pretty amazing. Generally I would go through a traditional pair of boots or soles in a year. Given the amount of tread I had left on these, I probably would have kept on wearing them, but the soles were getting thin enough that I was at risk of putting cactus and mesquite spines through them. The stitching on the soles was just starting to come apart. The glue was holding, but I was starting to see a little separation of the soles at the toes.
I will say that the durability, I’m seeing on these may not track for everyone. I live in really dry country. I think if they are getting wet all the time, you’d be more likely to see the uppers start to crack and come apart and the soles delaminate from the shoe. That said, the soles on these are as durable as anything I’ve ever used. Part of that is that the rubber is really hard and abrasion resistant, and the other part is that you don’t have a midsole to crush or start to walk out on.
Anyway, I started wearing my second pair in May and will report on how the rebuild goes on the first.
