I live in the United States in Texas and have purchase now 3 pairs of boots from Unterwegs. They have great customer service. On this last pair I got the other day, there was a small delay and they discovered it and got my boots out the door within an hour.
I will continue to buy from Unterwegs for the rest of my life. If they don't have it, they will get it as in the case of my newest boots, Meindl Klosters Identity. They are great boots by the way.
When you order, say hi to Stefanie Schmidt and Michael Weidhüner for me. Both are great customer service persons.
