I've had numbness in my toes and the balls of my feet for 13 years, since I was 53. It was diagnosed as Morton's Neuroma by my family physician, but foot x-rays showed no evidence of that condition.
My father, aunt and brother all have or had this condition, with onset in early to mid 50's. Neither they nor I are or were diabetic. There is no evidence of circulatory problems. By the time he died at 83, my father's numbness had progressed up his shins nearly to his knees,which I'd like to avoid. At this time, my condition is not so severe, merely annoying.
Interestingly, except for a small spot between my first and second toes, I am able to feel even a light touch on my feet. The numbness seems mostly "internal", not on the surface. I'm able to induce tingling in my toes by scratching my instep.
I have normal arches and no noticeable external deformities, though my podiatrist says my feet are "pretty beat up" from years of running and basketball.
