A tubular device typically worn on the feet of a diabetic patient intended to help maintain foot health and promote wound healing through specific design features (e.g., non-binding cuff, no/flat seams, moisture control materials, and/or non-wrinkling materials) combined with a special therapeutic feature (e.g., inclusion of fibres intended to absorb patient electromagnetic energy and return energy to the patient to help increase vascular flow and oxygen levels in the blood). The device is intended for daily use in the home and healthcare facility. This is a reusable device.
