Peter, I ran into this issue a couple of months ago and opted to contact Alden about it. I sent them pictures of the blotches and asked what they were and whether anything could be done to 'fix' them. Alden sent me a mailing container, re-dyed the shoes and got them back to me in less than three weeks. They look much better now. I have some before/after pics that I will post in a day or two.
