The metal is lightweight yet strong. Great product for a great price. My ears get blocked every year or so. What more could a person ask for! I?m almost certain they are just sending whatever they have in stock . Zum Klang / Zur Verbindung:Er hat einen sehr ausgewogenen Klang und ist damit für alle Musik Genre geeignet. They are also super comfortable and don?t fall out when jogging (unlike the pair I had before). As I took off, I didnt really feel it again until I got to the next red light, and the misfiring got worse. I wanted the regular Berkinstock Arizonas and would have had no problem paying the $89 that they probably would cost, but nowhere on Amazon could I get size 46, so these were the only 46s I could find and decided to give them a try. This is my 4th pair of Keens.
