Abstract: A protective foot cover for use in dance, exercise, or athletic applications using strategically placed protective pieces in ball and heel areas of the foot in connection with an elastic material in the sole structure to allow the foot to move freely and provide less of a barrier between the foot and floor such that a dancer can better sense the floor upon which they dance. The foot cover incorporates strategically placed protective patches that provide support, protection, and comfort to the ball and heel portions of the foot. The patches are spaced from one another so that the footwear is able to move more naturally with the expansion of the foot as pressure is applied to the foot. An elastic band extends in a figure eight configuration from the front of the cover, beneath the arch of the foot where the band overlaps, and around the heel to provide arch support and to hold the cover on the foot.

Abstract: A modifier material and method for making the same is characterized by the addition of a partitioning agent to a polymer material such as synthetic rubber to prevent reagglomeration of the rubber. The partitioning agent reduces the time required to disperse the modifier material in a material to be modified and also reduces the viscosity of the modified material so that the modified material is easier to handle. The partitioning agent preferably includes a mixture of phenyl formaldehyde resin and precipitated silica gel.

Abstract: A porous semiconductor is created by electrochemical etching. Selected regions of a semiconductor are first treated to reduce the threshold potential at which pore formation occurs, and then an electrochemical etch is carried out on the semiconductor at a potential at least equal to the reduced threshold potential for the selected regions and less than the threshold potential for untreated regions. The selective treatment preferably involves implantation with the same ions as the semiconductor, i.e. Si ions for silicon. The treatment results in the formation of highly defined etch patterns or patterns of porous material depending on the process conditions.
