Like the spray off a spinning car tire, the motion of running picks up water from the ground and drops it on your feet.

Solution
A small fluid dynamic device, The Grunge Guard, can be put in the path of the water to change the trajectory of the flow. Instead of continuing up the shoe, it is projected away. See how at www.nuumo.com

  • Great gizmo, great tune -- to dry feet!

  • I think this is great, v. styling. And I'd say so, even if I were not pals w/his sister!

    Cool video, and I'll pass this along to friends.

    take care,

    Bridget
