I have ridden DeeLux/Raichle boots for nearly 2 decades, thought I would try something different...reading your posts last year also influenced my original purchase of them.
Things I like about the UPZ:
Love the short sole length,
Well made shell and great liner
Slightly lighter weight,
I don't think the Upz boots are any better or worse than the DeeLux...just different...flex and fit.... I think I was just having stubborn "old dog, new tricks issues".
