5 in keens a 9 in ASICS and Nike never fit, 8. My ONLY issue is that these are sold as "white". I heard people say that these shoes can wear for 12 years. Un punto que no me gustó tanto, es que debido a que los controles son touch, si rozas aunque sea un poco el audífono, se pausa o cambia la canción. When paired with the mojo they sounded like completely different set of headphones. I wish I could scream through this message that?s how mad I am. They block out sound quite well, is more comfortable than my wired earbuds. A super short headphone cable would suit me well. I got this for my mom. I will wear it to the Zion national park next week for hiking on the narrow.
