The ever common presentation of focal hyperkeratosis on the plantar aspect of the foot...how do you treat it and what kind of success rate do you see?  These are painful lesions that are often sub metatarsal head, but clearly distinct from a simple shear or pressure callus.  I usually treat them with debridement and custom orthototics with offloading to the site of the lesion(s).
