Runs a bit large so I ordered . I keep this in my kitchen storage cabinet and it fits nicely. I want to mention that the instep is high, and there is ample room. *The Sangy* i love these earbuds! latly the design have been over sized n weird designs. These stay in place, probably wont last forever, but theyll do for a good while and the price is spot on! Even after a crazy 12 hour shift, my feet dont hurt at all. What was a big deal the toy broke in less then 2 hours of being played with my son dropped the toy on the floor and its arm broke off. I never buy any other brand since trying on my first pair 12 yrs ago.
