The mathematical model shows that if the hairs bend at an angle closer to horizontal, the surface area that the geckos can stick to increases, and the geckos can support more weight.
Setae are also ultraflexible. When a gecko jumps to another surface or quickly changes direction to escape a predator, its toe hairs must absorb huge amounts of energy and redirect it. The flexibility and stretchiness of the setae help redirect the energy and make it possible for geckos to walk across surfaces at any angle, unless the surface is covered in too much moisture, in which case their sticking powers are reduced and their feet start slipping.
Setae that are too flexible or setae that are too long would get tangled up and cause geckos to slide and fall off surfaces, Greaney said. The model also showed that geckos are able to balance out the force of gravity by applying their own force to a wall; they can press and slide their feet toward their body and drag their feet across surfaces without falling.
Greaney said the next step is to explore the role that friction plays. However, we do not guarantee individual replies due to the high volume of messages.

The setae are curved inward, toward the center of the foot. When the gecko pulls back a toe, the setae get straightened. Explore further.

The other view took the Van der Waals force direction. I think both views make sense unless they are proven otherwise. These views should also be the reason for the crested gecko sticky feet. Geckos reproduce by mating, The male gecko holds the skin of the female gecko on his necks and wrap his tail around the female tail bringing their mating organs together.
Some other species of gecko reproduce by laying eggs without the help of the male. Most sticky geckos live in humid areas, which increases the stickiness. Geckos climbing feet is the reason why they can climb on surfaces while you cannot.
Researchers have who worked on this idea of climbing feet and have developed some technology to sealing of wound without stitching and some nanotechnology to develop sticking gloves that resemble use the sticking idea of geckos. This will help soldiers walk on walls someday. Geckos feet specifically help them climb on surfaces without falling off. This is made possible by the tiny hairs known as setae found on their feet.
These sets are flexible enough to help the geckos to make abrupt turns and stick when they jump. The flexibility helps the geckos to redirect the energy built up. Some researchers have worked on developing biomimicry technology. They are also working on a technology to seal wounds without stitching. I think the idea behind this should be the attraction of molecules of the same kind.
