The comments so far are that they understand the leaf idea but perhaps it's distracting from the form of the foot. If you removed that part yet still somehow kept the shape of the foot and the product, it may work better.
#159 is interesting but Yin/Yang immediately comes to mind which is a bit overused. The leaf idea was good but perhaps a better representation and seperated from the foot. Perhaps make a leaf the background, somehow shaped like the product, with the product name floating over the leaf? Maybe add water droplets on the leaf to show cleanliness?
