I will be wearing them to the zoo. I read a user review prior to ordering them. They hurt in the arch and the metatarsal area. Hier hat der Designer sehr gute Arbeit geleistet. So I would consider sizing up. The elastic for the front bottle came away so I?ve had to re-sew it back on. I followed instructions in the manual and I removed all traces of software from my old mouse. Googling for ratings and reviews, I came up with UE Boom 2, JBL Charge 3 and Bose SoundLink Mini II as the frontrunners from nearly all reviewers. They are extremely lightweight and comfortable. Just dont put this underneath metal or it will obstruct the signal
