They stay on! I was very hesitant to buy another pair, because many companies change their product and i was, well, afraid to part with my Tevas after 12 years of use! I have been using it for just over a week now and I am very happy with the purchase. PERO EL EMPAQUE BIEN EL CELULAR FUNCIONA PERFECTAMENTE ASI QUE CUMPLIO MIS EXPECTATIVAS IST ES ABER NICHT! In my opinion it still feels a tad narrow compared to other NB products; its wide enough, but not as wide as their athletic shoes. All parts were included and shipped fast. No marking on either side, and both sides look identical on the inside and out. I didnt buy a 5. I have to say for the price around $25 you can?t beat them!
