Nice. I've read a ton of good things about chromepak soles. I've seen posts on various forums about 2-3 years of regular wear on pavement with no issues. I haven't, however, read anything about extensive use on wet surfaces or in the rain. I'll try to keep mine dry to play it safe.
Mine have seen a good amount of summer rain, and have been soaked through at least twice. I did treat them with AE waterproofing spray before their first wear since I knew they would be my go-to shoe and see inclement weather, and I think they have held up pretty well over the past season of wear.
I just VSC'd mine and took a few shots, including one of the soles to give an idea of the potential wear. I have done a good amount of walking in these, including a few days exploring San Francisco, and the soles still look good to my eye.
I really should trim the laces back more.
The only caveat I'd throw out there is that the shearling inserts came loose a few months in, but a few drops of Gorilla Glue reaffixed them and they haven't budged since. I do not know if this will affect Quoddy's ability to retain the shearling when it's time to re-sole them, but if I have to lose the inserts I am fine with it.
