Abstract
An ambulatory support and traction device used as a flexible foot (1) added to a walking aid, such as a cane or crutch (6), is provided. The flexible foot (1) includes a bendable coil or spring (3) that allows angulation of a walking aid shaft (4) relative to the foot (1) without the loss of adherence of the foot to a ground surface (19). The allowance of angulation of the walking aid shaft (4) improves ambulatory support and balance when leaning on the walking aid or when traversing an inclined surface and can assist the user in rising from a sitting position to a standing position without repositioning of the foot. The flexible foot (1) has a rigid base (2) for structural support and a traction sole (17) to adhere to surfaces both indoors and outdoors and on different surfaces and environments.
