Teniendo el pie ancho y con calzado entre 28. They didn?t rattle or shift at all. I had to be very careful So I didn?t damage my EarPods case. The cord is to short and it?s cheaply made. I always appreciate the under-promise/ over-deliver philosophy. It?s such a great design idea, but so poorly executed. I bought the size 8 because I wanted to wear thick socks in them, as I have had to do with other slippers I have bought in the past. Highly recommend these Nikes for your next sneaker purchase ladies. Maybe reduces it, but that would be all. Ive always been a speaker gamer, never used headsets.
