Thats why I have return it next day. These sandals are very well constructed and look like they will last me 20 years. They do cut into the heel a bit, but I think that will loosen up with break in and over time. a 10 almost surely would be fine though! An HD class closed headphone was exactly what I was looking for. I bought the Avantree knowing that I would have to dedicate a bottle cage to this speaker instead of hanging it from my handlebars. I truly hope they saw their ways and apologize. I wore it for my bachelorette party at the lake and during my honeymoon in Jamaica. Ditto on the comfort of the headband. Finalmente lunico modello per la pianta stretta che anchio posso indossare.
