Query: Haven't lost anything yet

Great for running. I've used mine for a year and a half now and it's about time I replaced it because the velcro has gone a bit. You lace the strap through your shoe laces and then over the top to the velcro Keys go in the pocket and cards go in the elastic strap on the back. It's a little silly that they made the pocket tapered so that you can't put your cards inside it but this thing is a lot better that putting my key in my bra like I was doing before.
