It is difficult to find any comprehensive information on these little known chakras. I have been able to find a bit, and will add more as I find it.
From wikimystica.org ~
There are said to be a series of 7 chakras below muladhara [root chakra] going down the leg,
[Satguru Sivaya Subramuniyaswami. Merging with Śiva: Hinduism's contemporary metaphysics, p.231] corresponding the base animal instincts, and to the Hindu underworld patala. They are called atala, vitala, sutala, talatala, rasatala, mahatala and patala.
This chakra is located in the hips, it governs fear and lust.
Located in the thighs, it governs anger and resentment.
Located in the knees, it governs jealousy.
Translated as 'under the bottom level', it is located in the calves, and it is a state of prolonged confusion and instinctive wilfulness.
Located in the ankles, it is the centre of selfishness and pure animal nature.
Located in the feet, this is the dark realm 'without conscience', and inner blindness.
Located in the soles of the feet, this is the realm of malice, murder, torture and hatred, and in Hindu mythology it borders on the realm of Naraka, or Hell.
Here is an article on the foot chakra~

The Chakra Energy System functions as a conduit through which divine energy passes into the spiritual and physical body. Without these energy portals, you would cease to exist because all energy comes from the Universal Source and is not derived from your own being.
Now, there are many of these energy centers located throughout your body. Traditionally there are seven major chakra. These seven energy portals rest at various points along the body: the base of the spine, the sexual, the solar plexus, the heart, the throat, the brow, and the crown (above the head). However, despite these seven, there are more that need to be examined. In this chapter we will start with the energy center that is left out, but is just as important as those seven. This center is the foot chakra, and let's call this center the zero chakra, just to keep with the conformity of the present chakra numbering system.
In a physical sense, the foot chakra is actually a split energy center, with each half sitting in the ball of each foot. If you were to place your feet together, these centers would seem to combine and make a complete energy center. However, regardless of whether the feet are physically next to each other, these split-centers, on each foot, are always linked and are always complete.
Now, the foot chakra is an important center in that it is here that divine energy returns back to the Source. It is the last point at which the energy is a part of you. Traditional thinking places the base chakra as this grounding point; however, that reasoning is not entirely correct. You see! The base (or root) chakra's function is more than just a grounding center. It actually functions as an energy transformation point where divine energy gets slowed down so that it can pass into the Earth quickly and effortlessly. While the base chakra does the actual conversion, it does not do the actual passing of the energy. Furthermore, the energy at the foot chakra remains elusive because this chakra, and the energy contained in it, has been nearly transformed into an Earth-based energy. Hence, as far as you can tell, the last place you perceive energy movement in the chakra system is at the base chakra, so you assume that no other major energy centers exist below it.
For example, if you could x-ray your energy centers and observe the energy stream as it enters from top, you would follow this energy as it slowly changed its form, as it passed from chakra to chakra. On this hypothetical x-ray, you would watch as the color shifted from the upper vibrations toward increasingly lower vibrations, as it passed from one chakra to the other. From thebase chakra to the foot chakra, you would not see a corresponding shift in color or be able to distinguish it from the background color of the Earth itself. However, if you were to adjust this x-ray a bit and examine for a flow of energy, instead of a color shift, you would notice a concentrated stream of energy reaching down from the base chakra and going into the foot chakra, where it would then swirl around for a bit and pass on into the Earth and back to ALL-THAT-IS. This swirling at the foot chakra is important and is a result of the amount of blocked up energy that can't freely pass into the Earth, and it is here the next part of our discussion begins.
An ideally, fully-open foot chakra would have no swirling whatsoever in it. It would pass energy out as quickly as it entered. Here, I'm speaking of an indefectible case and only the most adept individuals (like a Master) possess a foot chakra free of all blockages. In a more realistic sense, though, an open foot chakra will have a slight swirling going on at all times. This kind of openness shows an individual that has no trouble keeping his focus on the mundane. It also shows that this person integrates well with earthly structures and energy systems. These people are usually very healthy as the earth-based energy can pass quickly out of the body's energy system and take most of the built-up negativity out of the system before it has a chance to do any harm and possibly manifest as an illness.
On the other hand, a closed foot chakra, where a great deal of swirling is going on, shows a person that is in a blocked-up state. The energy has no place to go, so it backs up and leaks out of the other (higher) centers and into the surrounding aura and atmosphere, where it is then absorbed by the Earth Plane. This leaking is very undesirable because energy that does not pass through the foot chakra and exits through the other centers can not be used by the individual. This kind of leaking also carries away much positive energy and, as such, these people will often be tired, irritable, and unreasonable.
Also, with the foot chakra blocked, all the areas of humanness get affected negatively. The individual poorly integrates with peers and loved ones and can not understand other people's point of view. In an extreme case, such an individual will rebel against society and claim that everyone is after him and out to do him in. They become very fearful and may even resort to violence as a kind of defense mechanism to protect the little energy that they have that is still of use to them. Some types of destrutive behaviors stem from an extensively blocked-up foot chakra.
Of course, in the above, I am talking about an extreme case. With a very ordinary type blockage, you would see a very mild form of these kinds of behaviors. Children, for example, often exhibit the mild symptoms of a blocked foot chakra. They are often self-centered and selfish with their possessions and with dealing with other children. In many children, the foot chakra is not fully developed, so it can't effectively pass energy out. Energy tends to back up in them quickly. In fact, you can notice this backing up in spurt patterns. The spurts are due to children holding on to their divine energy too long and then when the back-up becomes too intense, they force open up their foot chakra and release the energy out in one lump sum. This holding/releasing pattern is normal in children, because they have not learned how to fully ground themselves. Eventually, as the child's foot chakra develops, and they ground better, they become more giving and tolerant of themselves and others. These spurts of groundedness and being blocked will dissipate as the child enters adolescence and eventually will be almost non-existent. ALMOST is the key word here because, as I said, many adults have blocked foot chakras (many of these cases stem from childhood), and, thusly, they will take on very mild forms of these childish patterns.
The cure, of course, is to open up the foot chakra and get it to pass energy as quickly as possible out of the entire chakra system and into the Earth. Many illnesses and adverse behavior patterns can be alleviated just by doing work on this chakra. Opening up this chakra requires the same techniques as used in opening up the other centers. The only note to make here is that a pendulum reading is not apt to give you an accurate account of what is going on in the foot chakra, as the blocked, swirling energy can fool the pendulum and make it swing to indicate and fully open condition, when, in fact, the center is closed up.
A better way to determine if the foot chakra is blocked is to have the patient lie down on his/her back and put his/her feet upright with a 3 to 6 inch space between the feet. Next you need to place your hand just above the energy field of the foot chakra. This will be somewhere between 3 to 12 inches above the tops of the toes, centered over the gap in the feet. At this point, you want to take a temperature reading, using the palms of your hands as a thermometer. A very warm energy reading will indicate much swirling of energy and a blocked up center. A very hot reading indicates a completely blocked center. A nice cool reading, with a faint tingling sensation in the palm of the hand, indicates an open center that is satisfactorily passing energy out of it. Here, of course, I recommend you feel what a good, clear center is like before you can tell what a blocked center feels like. Very quickly, you will develop a natural affinity for the way it feels when your hands are near this energy center.
Also, if you are able to see fine aura, you can observe for a blocked foot chakra. (With the word 'fine' here we are referring to being able to distinguish between the Earth's background energy field and that of the grounded energy passing out of the chakra system.) With this technique, you should direct your attention to between the feet and look for dark swirling, wispy, like streaks. A good clear foot chakra will show only one or two of these swirls. A blocked one will have more. A fully blocked foot chakra will be seen as a solid darkness that just permeates between the feet (you may not need to see fine aura to pick up on this one).
People tend to get a blocked up foot chakra when life gets a bit too much for them. The increase in mundane activity backs-up energy in the foot chakra because the individual is not used to clearing this increased amount of energy flow. Quickly, a sense of fear or anticipation can pervade, as the other higher centers begin to leak energy out into the aura. People experiencing the onslaught of this condition will report an increase in sensitivity all over the body. They may become very emotional or even extremely intellectual, depending on their core makeup. Exercise can help here to alleviate this condition, temporarily, but eventually this energy center will have to be unblocked to permanently alter the condition. The other fix is to return to previous levels of mundane activity, which is undesirable because, if the individual is experiencing a growth in activity, it is likely that the person is ready to handle things on a more increased level.
Now, normally, this energy center will learn to open up on its own, when an increase in activity comes about, and it then passes the expanded energy flow out, returning the individual to status-quo, after a short period of discomfort. But, in some cases, possibly because of fear or because of not wanting to let go of old patterns and ways, this natural opening-up process does not occur and the individual gets forced to take a step back, thereby retarding their own growth. A trained energy practitioner can unblock this chakra very easily and see the results in the patient's life almost instantly. Many people who engage in intense spiritual development will experience this cycle of the foot chakra blocking up and then unblocking. They often feel like a yo-yo being pulled up to ecstasy one moment and then being gripped by fear of the unknown another. Again, the simple cure is to unblock this chakra.
To unblock this chakra conventional healing techniques will work. I will not be covering standard healing practices in this chapter, but, for those people that are not familiar with how to do this kind of healing or for those people reading that just want to be able to clear their own center, I have a procedure that will work quite nicely, under normal conditions and for normal blockages.
Get a standard clear drinking glass and fill it with two or three table spoons of sea salt. Fill the glass with water and mix up the salt and water until no sea salt remains. Now lie down on the floor on your back and place the glass of sea-salt solution between your feet. You could also sit in a meditation position and put the glass near-to or against the balls of your feet. The idea is to immerse the solution in the center of the Foot Chakra's energy field. Now, lie back (if you are lying down for this procedure) and relax for three minutes or so. The sea salt solution will begin to pull any energy blocks out of the center. Now, after several minutes, sit upright, if you were on your back. And use your hand, and, in a swirling motion, hover it above the glass of sea-salt solution and above the energy field of your foot (this action may take a bit to get used to, especially if you are not too flexible). This swirling distance of your hand should be no more than 6 inches above the tops of your toes. Continue to swirl this energy around for another minute, to coax the last of the blocks out of the chakra and into the sea salt solution. The procedure is complete! Now pick up the glass and yourself. Throw away the salt-water solution and wash the glass thoroughly before using it for human consumption.
This method will free up most foot chakras, especially if you have just increased your activity or picked up some stray negativity that you are having trouble getting rid of. I recommend the sea salt solution for non-energy practitioners, as it is a fail-safe way of doing the procedure, especially for those people that are not too adept at moving energy or energy fields. Dry sea salt could also be used too, but you would need a larger concentration of salt (like an entire glass), as the water acts as a natural catalyst to bind the negative energy globs to the salt particles.
Well this concludes this little chakra chat. .
