My 8111's are approaching 3 years old. Apart from an early treatment of mink oil, I have just taken them to the Red Wing store every Spring and Fall for a free oil treatment and free replacement laces. I'm due for the service now.
These are EXTREMELY comfortable. I wear them 3-5 times per week, and even 2-3 times per week during the brutal Texas summer. Cedar shoe trees every night. The leather has become very soft and the boots are waterproof with the oiling. The soles are wearing very well, and work year round for me unless I'm dealing with snow and ice. I wear them when I travel now that I have TSA Pre-Check and don't have to take my boots or shoes off to clear security. They are getting some nice patina and indigo transfer from denim. Getting better with age!!
Cheers!
