The construction of the bodypack is not super well constructed like a Shure, but weve been gigging with them for 2 years and they all still work. :D I was able to get it to charge, it held well in its charger, I was able to up load songs to it w/o a problem. Heels are not too high or too low just the right size. I do know that when I switch to my phone during those complaint calls, I get good responses. The arch support is similar -- noticeable at first but I acclimated quickly. Zipper on the organizer bag was "wonky" but I think its okay now. It was very comfy. Very please with these shoes I wear only birkwnstocks due to foot pain if I wear other shoes. The green aventurine might be real, but it has dye spots so I highly doubt it (propabably grey agate dyed).
