Plantar fasciitis.

Hallux rigidus is a “stiff big toe joint”. Patients with this condition, which is a form of arthritis, often report that it feels as if they have to force their big toe to bend at the joint when “toeing off” from the ground while walking. Often times, hallux rigidus results in the joint becoming completely rigid. Movement of the big toe joint occurs typically in an up and down plane only. The upward motion is dorsiflexion and the downward motion is plantar flexion. The normal upward movement is approximately 70 degrees and the downward movement is about 25 degrees. You need at least 60 degrees of upward movement of the big toe joint to prevent limping.
