I returned it and bought size 11 which is very very comfortable. They are great at noise canceling too it thats what youre into. After few use, the phone holder breaks that destroyed my phone. Ob die preislich über diesem Schuhwerk liegende Sandale meine Erwartungen entsprochen hätte, ich will es nicht mehr herausfinden. I?ve never had an issue pairing with any device, and going between them is easy. Geniale Teile! Returned within a few days. I give credit to this part for the adhesive and sense of security it had. Very nice bike rack, very sturdy when properly mounted (mounted on my Lexus GS 350 and fits nearly perfectly). I started on the first set of hooks for a few days before going to the second set.
