i would highly recommend balance therapy. It helped me greatly not so much to avoid losing my balance but to help prevent actually falling when i did lose my balance. both my feet up to half way up the calves are dead numb. The numbness also continues past my knees. do a little research to find out what physical therapy places are well equipped to do this type of therapy. There are harnesses and machines that are used to simulate walking on uneven surfaces, to catch yourself when you lose your balance etc.
