I live in the US.
What's the deal?
+1 on the re-dye from Alden. I had pitting issues with my PTB and Alden did a great job refinishing the shoe. The color became deeper and I'm sure they re-dyed it. I got my shoe from Sherman Brothers so they facilitated the process with Alden. Considering that you did not get it from a retailer, you'll have to try to contact Alden directly. Which I think may be your bigger issue because in my experience the Alden factory prefer to deal with their retailers. Good luck! I hope you can correct the issue.
very interesting! I had the same thing on these exact boots. Mine have been worn about 18 times (OCD). The blotches are only really noticeable in bright light. And I'm pretty sure I did not spill any liquid on the boot (just one boot has the spotch).
