Got a plantar injury?  Best bet is that its plantar fasciitis.

The plantar fascia is often a tough, fibrous band of connective tissue that runs from the heel bone towards ball in the foot. It plays an key part inside the normal foot mechanics whilst running, jumping and walking.

Plantar fasciitis or inflammation with the plantar fascia comes about when the plantar fascia suffers microscopic tears at the point where it joins towards the heel bone, or along its length. With poor foot mechanics, too much use or other risk factors, the pressure applied towards the plantar fascia during running and walking and the shift of body weight from one foot towards other can tear the fascia from its attachment for the heel and result in microscopic tears.

Plantar fasciitis is usually a severe condition. At its most extreme, the most severe of plantar fasciitis can result in ruptures in the ligament.
