These are by far the best looking Crocs I have BUT they are the most UNCOMFORTABLE crocs I?ve ever owned . Like literally on the dot! If you dont want to connect to bluetooth, you can tune in to local radio stations. All of this in a device that costs a fraction of what the major brands cost. Die Soundqualiät ist keineswegs schlecht, aber eben auch nicht extrem gut. If I can build this anyone can. The quality and comfort is exceptional! The UP cannot pass for leather even at a distance. I would recommend Birkenstocks to anyone for this reason alone, and to make the deal even better, they make waterproof work shoes such as these. 99 from Tozo last year.
