Augmented Footwear for Gripping and Holding in Micro-gravity Environments

Abstract

This invention relates generally to human space flights to Earth orbit and beyond. It is designed for use in micro-gravity environments, to allow the wearer to make use of one or both feet as prehensile appendages. The invention enables the operator to use their feet for gripping, holding and manipulating. It achieves this by means of flexible footwear with molded extensions that protrude from under the toes and ball of the foot, creating additional leverage for the flexion and extension of the toes. The basic embodiment of the invention consists of six (6) main components. 1. A solid extrusion, positioned under the metatarsal bones of the foot, extending downward from the plantar surface. 2. A second solid extrusion, positioned under the first phalange of the foot, extending downward from the plantar surface. 3. A third solid extrusion, positioned under the second, third, fourth and fifth phalanges collectively, extending downward from their plantar surfaces. 4. A foot covering, encompassing the phalanges and metatarsus of the foot, and integrating the three extrusions. 5. A means for anchoring or securing the foot covering to the user's foot. 6. A means for allowing full flexion and hyperextension of the phalanges, and by extension, the extrusions positioned under the phalanges.
