Turning now to the drawings, FIG. 1 illustrates a block diagram depicting selected elements of an embodiment of a shoe 100 including a packet 114, which may be enclosed within a pocket of shoe 100. In FIG. 1, shoe 100 may be an athletic shoe including a running shoe, a jogging shoe, a walking shoe, a tennis shoe, a hiking shoe, a cleated shoe, a bicycle shoe, or another type of athletic shoe. Shoe 100 may also be another type of shoe. Shoe 100 may include a non-weight bearing portion including a tongue portion 122 of a tongue 112 of shoe 100, a toe portion 124 of shoe 100, a sidewall portion 126 of shoe 100, a heel portion 128 of shoe 100, an ankle portion 130 of shoe 100, or another non-weight bearing portion of shoe 100.

Packet 114 may include a packet material including one or more of cotton, silk, polyester, a hybrid paper, or another type of packet material. The packet material may allow water, moisture vapor, and odor to be transmitted through the packet material of packet 114. Packet 114 may also include particles of microporous desiccant material. The particles of microporous desiccant material may include one or more of a naturally occurring Zeolite, an industrially produced Zeolite, silica, an activated charcoal, a calcium sulfate, a calcium chloride, or another type of desiccant material. Particles of microporous desiccant material are porous and may have multiple pores within the particles. The pores within the particles may absorb water, moisture, and odor exposed to the particles. The particles may also expel water, moisture, and odor from the pores or let the water and moisture in the pores dry when the particles are exposed to air circulation. The particles may also absorb and expel ammonia nitrogen from the human body. This cycle of absorption and expulsion of water, moisture, and odor may be repeated again and again, and may allow packet 114 to outlast the useful life of shoe 100. Packet 114 may further include an odor reduction material including a deodorizer, an odor neutralizer, a perfume, a fragrance oil, aroma chemicals, aromatic resins, another type of odor reduction material, or combination thereof. The odor reduction material may have a pleasant aroma and may reduce odor within shoe 100. When packet 114 is enclosed within shoe 100, the particles of microporous desiccant material may absorb moisture, water, and odor when a foot of a wearer is within shoe 100. The particles of microporous desiccant material included in packet 114 may also expel moisture and water and dissipate odor when air circulates within shoe 100. The particles of microporous desiccant material may have a particle size, which may allow the particles to maintain their porosity. For example, the particles of microporous desiccant material may be between 3 mm and 5 mm in size.

Packet 114 may be inserted in an opening of a pocket of a non-weight bearing portion of shoe 100. Packet 114 may be enclosed within a pocket of shoe 100 when the opening of the pocket is sealed using a fastener. The fastener may be a Velcro fastener, a button fastener, a zipper, an adhesive, sewing thread, or another type of fastener. For example, packet 114 may be inserted in an opening 116 of a pocket of the tongue portion 122 of shoe 100 and enclosed within shoe 100 by sewing opening 116 of the pocket shut using sewing thread. Sewing thread may be a cotton thread, a silk thread, or another type of thread. In one or more embodiments, packet 114 may be removed and replaced when opening 116 of the pocket uses a reusable fastener, e.g. a Velcro fastener. A shape, dimensions, and size of packet 114 may allow packet 114 to conform to a shape, dimensions, and size of a pocket of shoe 100. Packet 114 including the packet material, the particles of microporous desiccant material, the odor reduction material, and the fastener may be hypoallergenic, biodegradable and environmentally friendly. Packet 114 may also reduce or kill bacteria and inhibit pathogen growth.

The non-weight bearing portion of shoe 100 may include padding. A portion of the padding may be between packet 114 enclosed within the pocket of shoe 100 and a foot of a wearer of the shoe. A portion of the padding may also include packet 114. The thickness of the padding between the foot and packet 114 should be minimized to increase the ability of packet 114 to absorb moisture, water, and odor from the foot while still allowing the shoe to be comfortable. The padding may also have a space or a slot within it that may allow packet 114 to be enclosed within a pocket of shoe 100 without increasing the overall thickness of the padding. Enclosing packet 114 within a pocket of a non-weight bearing portion of shoe 100 may reduce or eliminate discomfort of a wearer of shoe 100 that might otherwise occur if packet 114 were enclosed in a weight bearing portion of shoe 100, e.g. the sole of shoe 100. Enclosing packet 114 within a pocket of a non-weight bearing portion of shoe 100 may also prevent damage to the particles of microporous desiccant material included in packet 114 due to impact of a foot on a weight bearing portion of shoe 100 while a wearer of shoe 100 is running, walking, or performing another type of activity.

In one or more embodiments, multiple packets 114 may be enclosed within multiple pockets of non-weight bearing portions of shoe 100 that may increase the amount of moisture and water, and odor that may be absorbed and subsequently expelled from shoe 100, and increase the amount of odor dissipated from shoe 100. The multiple packets 114 may also further reduce the odor within shoe 100.

FIG. 2A is a partial front view of tongue 112 of shoe 100 including packet 114. Packet 114 is shown partially inserted in an opening 216 of a pocket 218 of tongue 112. The particles of microporous desiccant material are enclosed within packet 114 with sewing thread 222. Sewing thread 222 may be made of a thread material including one or more of cotton, silk, polyester, or another type of thread material. Packet 114 may have a shape, dimensions, and a size that allows packet 114 to be enclosed within pocket 218. The shape of packet 114 may include a square shape, a rectangle shape, a circular shape, or another type of shape. The dimensions of packet 114 may be 1″×1⅝″×0.125″, which is approximately 3 mm, or other dimensions of packet 114 that fits within pocket 218. Packet 114 may be the size of a postage stamp, a tea bag, or another size that fits within pocket 218. Pocket 218 may have a shape, dimensions, and a size that allows packet 114 to fit within pocket 218. The dimensions and size of packet 114 may allow an effective amount of the particles of microporous desiccant material to be enclosed within packet 114 for moisture, water, and odor absorption. The weight of packet 114 including the particles of microporous desiccant material may be minimal given the size of packet 114. Packet 114 may not add any additional weight or size to shoe 100 based on the minimal size and weight of packet 114.
