Mike,
I had delamination and wear issues with a pair of Lowa Zephyr GTX Mids last year. I sent them back to Lowa and they said normal wear. I submitted pictures of the same model boot I bought 9 years earlier and wore all over Afghanistan in 2012-2013 for wear comparisons. They decided to send me a new pair free of charge and these are wearing much better. Seems some boots makers have off days too.
