Get a grip!
This ingenious gadget is designed specifically to clean out the dirt, debris and other cruddies that invade hook-and-loop fasteners. Use the wire-side brush to clean your hooks, the soft-side brush to loosen your loops. Voila, a nearly air-tight bond. And here's a bonus: this pocket-sized tool also includes a boot pick to eject those irritating, freeloading pebbles from your tread.
