Abstract
This invention provides a sock containing a coating material such as a coloring agent or dye, applied to at least a portion of the interior surface of the sock for sensing pressure points on a patient's foot to which the sock is fitted. The sock is placed on the patient's foot to cover preferably the entire foot, but at least the bottom portion thereof. The sock is removed after being worn for a period of time, and in those areas of the foot susceptible to pressure points, the coating material transfers from the interior of the sock and adheres to the foot in those points. The present invention is particularly applicable to a person having diabetic neuropathic feet wherein portions of the foot may be insensitive to pressure and therefore must be protected against pressure sores.
