The tendons in front of your ankle can sometimes become irritated when your shoes are laced too tightly. This can also compress the nerves in this area, resulting in occasional numbness, but most often the problem is pain. Of course, injuries to ligaments or bones can also cause pain in this area. Try skipping the top lace completely rather than lacing it looser. You can then lace your shoe securely without irritation. Odds are this should help a lot. If this simple solution doesn't work, have your foot examined by a sports medicine practitioner.
