Ever heard of the Babinski Reflex? This is a reflex of the foot in which the toes curl back rather than crunch when the sole is stroked. So, it is not true that the toes always or usually crunch up when the soles are tickled. Some girls crunch their toes, some curl and spread them, and some do nothing at all when their soles are stroked. Bottom line, I see foot tickling as an erotic art form. I am not so much concerned with how much of the responses are fake as how sexy and realistic the toe and foot movements appear to be during the tickling. There is a divide amongst the foot/tickling fetish crowd. Those who are more on the tickling end of the spectrum get off primarily on tickling and insist that every response during the tickling be authentic. On the other end of the spectrum are those who are primarily foot fetishists who think that the responses to the tickling (in terms of sexy toe movements, etc.) bring out the beauty and sexiness of the female foot. I am amongst those in the latter group. So, my concern is not so much with strictly authentic responses to the tickling as the eroticism of sexy toe movements when the soles are stroked. The authentic response of some girls is not to move their toes at all, or to keep them crunched up throughout the clip. It boils down to whatever floats your boat. The offerings of the foot tickling clip producers are broad enough to satisfy everyone. So, I repeat my request...please let me know if anyone has seen any foot tickling clips which feature sexy toe movements in response to the sole tickling, even if it is not strictly authentic. Erotism is different for everyone.
