This is a growing problem that affects the navicular bone of the foot in young children. Its not clear what, but something appears to disrupt some blood supply to the bone and a type of necrosis sets in. The navicular is at the high point of the arch, so it is subjected to a lot of pressure and this may account for the problem. The most common age of onset is around 5 years and it may cause limping. The pain can usually be located to the navicular bone. Often on x-ray, the bone appears much more narrower than the unaffected side. Usually this needs to be placed in a walking cast (more) to protect the foot and its growing bones. After the cast is removed foot orthotics are often used (link) to further protect the weightbearing on the navicular bone.
Poor circulation puts the foot at great risk for a range of problems and those with it need to take great care to prevent minor cuts and scratches from becoming more severe problems. If you have poor circulation you really need to watch the diet, have your doctor check your cholesterol and start a gentle exercise program to prevent it getting worse and hopefully reverse it somewhat.
You also need to take precautions. The biggest problem with the poor circulation is the risk of some damage not healing. A minor scratch can become a major wound that does not heal. So good footwear is needed to make sure that no problems happen as a result of poor fitting footwear. Care needs to be taken to prevent trauma or damage. If a wound does develop, it needs appropriate care, preferably from a health professional to prevent it becoming a more severe problem. The worst case scenario is that an amputation of a limb is needed if it gets that bad. The risk is not worth it and early treatment of any problems is extremely important.
There is some good advice here from ePodiatry on poor cicrulation and links for advice here.

On the internet there is plenty of information on the topic, and not all of it can be trusted. Here are some of the sites to get information about this:

Yes, you read right, there is such a thing! The Fish Pedicure has been in the news a lot lately, mostly for its novelty value. A number of spas in Asia have been offering this for a while now and a few salons in the USA have started to offer it. The whole idea of the fish pedicure is to improve foot health by using the small fish species, Gara Rufa to eat the deal callused skin on the fish. They have been label the ‘Dr Fish’ because of this activity. The fish are supposed to just eat the callused and dry skin on the foot and leave the normal skin alone. It is a squeamish way to get a pedicure and is certainly not for everyone. There is no research on the effectiveness of this approach, but there are plenty of testimonials as to how well it works! The only problem that is emerging is the risk of infection which has led some regulatory agencies to shut some spas down and in some cases, ban them all together. The main concern is over infection control issues related to the fish themselves and the use of the water that they are in. If you are considering a fish pedicure, then this infection risk needs to be taken into account, especially if you have any broken skin on the foot.
