I asked a bunch of foot fetishists (they were in New York for the annual Foot Ball where the featured attraction was the contest for Best Foot Strip Tease). Even smaller structures at the ends of the setae, called spatulae, make such close contact with the climbing surface that electrons in both materials interact, creating a type of attraction called van der Waals forces. Mechanical engineer Elliot Hawkes of Stanford tested the new adhesive by strapping his feet to footholds connected to the patches through a rod. Neither Ms. Perez nor Ms. Tanaka believes that watching as much television as her son Sam does will lead to Although the scientists have tested only minute amounts of the material, they estimate that if its properties hold up on a larger scale, a dime-size patch of it could support 2 to 22 pounds, depending on how densely the hairs were packed. While not a professionally trained martial artist, she pursued ballet professionally and landed a spot at Londons Royal Academy of Dance. The researchers showed that the keratin fibers are aligned in the direction of the setae, which might help them resist abrasion.

Each of these hairs, known as setae, finishes in hundreds of even finer spatula-shaped split-ends. Those toes that maintained contact with the surface were able to shift orientation and better distribute the load. So a gecko patch's stickiness should increase if researchers can find a way to distribute forces more evenly. . Famous for their sticky feet, the gecko can run up walls and across ceilings as well as hang from a surface by its toes.
