My dog warmup I dont really like to use the fins, but must with this pair. I get so many compliments when I wear them and no one ever believes it when I say they are crocs. 10) FINALLY the surround sound effect is negligable. They dont flatten out after sleeping on them. With that said these shoes are just as good, comfortable and long lasting as my my Birkenstocks. Its absolutely glorious for acoustic guitar, but then, so is the 650. This is my second pair of Dasklos Franny. I was concerned it would be garish since the colors sre listed as orange and black but was pleasantly surprised that it is more of a brown-ish orange than an regular orange so it is still neutral looking and I actually like them. Ich finde ihn für das Geld nicht so gut.
