According to an example embodiment, a wearer of the protective footwear can selectively adjust the band closure system <NUM> (e.g., tighten, loosen, etc.) by selectively choosing which of the lower apertures <NUM> and the upper apertures <NUM> the lower band retainer <NUM> and the upper band retainer <NUM> engage.

As shown in <FIG>, the band retainer <NUM> defines an edge, shown as interior edge <NUM>. According to an example embodiment, the interior edge <NUM> of the band retainer <NUM> is configured to be selectively received by the band receiver <NUM> of the band interface <NUM>. As shown in <FIG>, the band retainer <NUM> is configured to releasably engage with the band interface <NUM> to selectively close the shin guard <NUM> and the calf guard <NUM> of the lower-leg engagement portion <NUM> together and secure the protective footwear <NUM> to a leg of a wearer.

According to an example embodiment, the ventilation system <NUM> is disposed within the foot engagement portion <NUM> of the protective footwear <NUM> and configured to facilitate (i) circulating fresh air from an external environment into the protective footwear <NUM> and (ii) removing warm and/or moist air from within the protective footwear <NUM> to the external environment. As shown in <FIG>, the ventilation system <NUM> includes one or more inlet vents, shown as intake vents <NUM>; one or more outlet vents, shown as exhaust vents <NUM>; and one or more tubes, shown as airflow conduits <NUM>.

As shown in <FIG> and <FIG>, the intake vents <NUM> are positioned at the toe end <NUM> of the protective footwear <NUM> and disposed along and/or within the mud guard <NUM>. According to an example embodiment, the intake vents <NUM> are positioned to receive an inlet airflow from the external environment. As shown in <FIG>, the intake vents <NUM> each include a permeable cover, shown as intake vent cover <NUM>. According to an example embodiment, the intake vent covers <NUM> are configured to be highly breathable, but highly resistant to water and/or debris (e.g., dirt, dust, mud, etc.). The intake vent covers <NUM> may thereby prevent debris, dirt, mud, water, etc. from entering the interior cavity <NUM> of the foot engagement portion <NUM> of the protective footwear <NUM> through the intake vents <NUM>.

As shown in <FIG> and <FIG>, the exhaust vents <NUM> are positioned at the heel end <NUM> of the protective footwear <NUM> and disposed along and/or within the heel cap <NUM>. According to an example embodiment, the exhaust vents <NUM> are positioned to facilitate the exit of air (e.g., warm, moist, etc. air) from the interior cavity <NUM> of the foot engagement portion <NUM> to the external environment. As shown in <FIG>, the exhaust vents <NUM> each include a permeable cover, shown as exhaust vent cover <NUM>. According to an example embodiment, the exhaust vent covers <NUM> are configured to be highly breathable, but highly resistant to water and/or debris (e.g., dirt, dust, mud, etc.). The exhaust vent covers <NUM> may thereby prevent debris, dirt, mud, water, etc. from entering the interior cavity <NUM> of the foot engagement portion <NUM> of the protective footwear <NUM> through the exhaust vents <NUM>.

As shown in <FIG>, each of the airflow conduits <NUM> extends along the interior cavity <NUM> of the foot engagement portion <NUM> between a respective intake vent <NUM> and a respective exhaust vent <NUM>. As shown in <FIG>, the airflow conduits <NUM> are disposed within the foot portion <NUM> of the core <NUM> (e.g., the sidewall thereof, etc.). According to an example embodiment, the airflow conduits <NUM> are manufactured from a material that is sturdy enough to maintain its shape, but soft enough to be comfortable against a foot and/or leg of the wearer of the protective footwear <NUM>. By way of example, the airflow conduits <NUM> may be manufactured from neoprene, latex, silicone, fabric, PU, PP, TPE, TPU, foam, and/or still another material. As shown in <FIG> and <FIG>, each of the airflow conduits <NUM> defines one or more slots, shown as slots <NUM>, along a length thereof. According to an example embodiments, the slots <NUM> are positioned to facilitate the entry of the inlet airflow (e.g., fresh air, etc.) from a respective intake vent <NUM> into the interior cavity <NUM> of the foot engagement portion <NUM> (e.g., to cool the feet of the wearer, etc.) and facilitate the exit of an exit airflow (e.g., warm, moist, etc. air) from the interior cavity <NUM> of the foot engagement portion <NUM> through a respective exhaust vent <NUM>.

As shown in at least <FIG> and <FIG>, the protective footwear <NUM> additionally or alternatively includes the ankle dampening system <NUM>. The ankle dampening system <NUM> may provide for a set range of motion (e.g., a predetermined range of motion) for the wearer's ankle. When a limit (e.g., a predetermined limit) of the set range of motion is met, the ankle dampening system <NUM> may provide a dampening effect by allowing for additional (e.g., a small amount) motion beyond the limit. The dampening effect provided by the ankle dampening system <NUM> allows for a limited range of motion of the wearer's ankle, yet provides a more comfortable experience to the wearer, as rotation of the wearer's ankle would not come to a jarring stop, but rather a smooth stop when the limit of the set range of motion is met.

<FIG> illustrate an example embodiment of the ankle dampening system <NUM>. For example, <FIG> illustrates an example embodiment of the ankle dampening system <NUM> coupled with the protective footwear <NUM>, <FIG> illustrates a detailed view of the ankle dampening system <NUM>, and <FIG> illustrates an exploded view of the ankle dampening system <NUM>. As shown the ankle dampening system <NUM> can be coupled with the footwear <NUM>, at for example, the pivotal hinge system <NUM>. The ankle dampening system <NUM> is implemented in addition to the pivotal hinge system <NUM>. The ankle dampening system <NUM> can be implemented as an integrated bracket on the pivotal hinge system <NUM>. The ankle dampening system <NUM> can define an elastomeric sprocket that allows for freedom of movement to a point whereupon a dampener limits a small amount of movement. The ankle dampening system <NUM> includes a dampening system support <NUM>, a hinge bumper <NUM>, and an enclosure plate <NUM>. The dampening system support <NUM>, the hinge bumper <NUM>, and the enclosure plate <NUM> may include central apertures 604A, 606A, 602A that are axially aligned and configured to surround at least a portion of the pivotal hinge system <NUM>.

The dampening system support <NUM> includes a recess <NUM> that receives the hinge bumper <NUM>. The recess <NUM> may include a notch <NUM> that extends from an outer perimeter of the recess <NUM> towards a center of the central aperture 604A. The notch <NUM> is configured to be positioned between legs <NUM> of the hinge bumper <NUM> to limit rotational movement of the lower-leg engagement portion <NUM> relative to the foot engagement portion <NUM>, but provide a dampening effect when one of the legs <NUM> contacts the notch <NUM>. The distance of the space provided between the legs <NUM> of the hinge bumper <NUM> may be the predetermined set range of motion of the additional rotational movement discussed above. The hinge bumper <NUM> may include various materials, such as plastic and may be formed by over-molding.

<FIG> illustrate another example of the ankle dampening system <NUM>. The ankle dampening system <NUM> can include a fastener (e.g., a bolt) <NUM> and a calf support element <NUM> (e.g., an elastomeric material) defining a recess in which the bolt <NUM> resides. The ankle dampening system <NUM> may allow for adjustment of the amount of dampening and/or amount of additional allowed rotational movement beyond the set range of motion (e.g., throw movement once the limit of the range of motion is met).
