First, check your shoes. Are they too tight or too small? Shoes can and will greatly influence your feet. In addition, check your socks to make sure they are not to tight causing reduced blood circulation. Sometimes the band at the top will be too tight.
For constant numbness the cause could be a more serious problem. Peripheral neuropathy is a condition that effects diabetics and can cause tingling, burning or numbing sensations in your feet. Neuropathy will affect the blood flow and can cause serious numbness and tingling in the feet, as well as other parts of the body.
It could also be caused by back or knee problems. Your posture could be causing the problem. Vitamin and nutrient deficiencies can also cause your feet to become numb or tingly.
If the problem persists, you should consult a podiatrist. Take note of exactly when the problem occurs (time of day, whether you are sitting or standing) and what activities you were doing prior.
