BACKGROUND OF THE INVENTION

Field of Invention

The disclosed subject matter is in the field of sandal or slip-on footwear.

Background of the Invention

Slip-on sandals, like flip-flops (e.g., FIG. 1, U.S. Des. Pat. D793,041 (issued Aug. 1, 2017)) or Crocs® (e.g., FIG. 1, U.S. Des. Pat. D535,088 (issued Jan. 16, 2007)), are a stylish and cozy style of footwear. However, slip-on sandals are typically not secured to a user's heel and, as a result, this style of footwear can either make it difficult for a user to make abrupt and complicated footsteps or else easily slip-off during undesirable circumstances. So, some slip-on sandals are provided with an optional-use heel-strap.

One type of optional use heel-strap for slip-on sandals is shown in FIG. 8 of U.S. Des. Pat. D838,467 (issued Jan. 22, 2019). The optional-use heel strap shown in that document is simply stuck to the midsole of a slip-on sandal and provided over a user's heel whenever its utility is desirable. A similar optional-use heel strap that is stuck through a slip-on sandal's upper is shown in FIG. 1 of U.S. D694,994 (issued Dec. 10, 2013). Unfortunately, this type of optional-use heel strap can damage the slip-on sandal and is, therefore, not entirely satisfactory in all situations. This type of strap has other drawbacks too, like, the inability of a user to hide the strap once the strap is placed on the slip-on and the potential for injury if the strap is placed on the slip on in an incorrect manner.

Another type of optional-use heel strap for slip-on sandals (like Crocs®) is shown in FIG. 3 of U.S. D732,808 (issued Jun. 30, 2015). The optional-use heel strap shown in that document is coupled to the upper and placed in a heel position when its utility is desired or else simply rotated out of the way over the sandal's upper when not needed. This type of optional-use heel strap can change the aesthetic appearance of the sandal and is, therefore, not entirely satisfactory in situations where a heel strap is wanted without a corresponding change in the sandal's appearance. Also, this type of heel strap is attached with a metal grommet which can be uncomfortable or rust.

Yet another type of optional-use heel strap for slip-on sandals (like flip flops or Crocs®) is shown in the figures of U.S. Published Pat. App. US2008/0189984 (published Aug. 14, 2008). This type of optional use heel strap is concealed in the sole of a sandal whenever the heel strap is not needed and otherwise exposed when its utility is desirable. A more elaborate version of this type of optional use heel strap is shown in the figures of U.S. Pat. No. 7,823,299 (issued Nov. 2, 2010). This type of optional-use heel strap can be uncomfortable and therefore unsatisfactory in some situations since it is not always possible to conceal a sufficiently padded heel strap in the sole of a slip-on sandal. Also, these types of heel-straps are difficult to reveal once put in a concealed configuration.

SUMMARY OF THE INVENTION

In view of the foregoing, an object of this specification is to disclose slip-on footwear with an improved optional-use heel strap. It is a further objective of this disclosure to provide an optional use heel strap to slip-on footwear without damaging the footwear. It is another objective of this specification to describe footwear with a heel strap that can be used or not used without substantially altering the aesthetic appearance of the footwear. Finally, it is an objective of this disclosure to highlight slip-on footwear with a concealable heel strap that is heavily padded.

In one embodiment, slip-on footwear includes a sole, an upper, and a padded optional-use heel strap concealed within a strap channel disposed around the heel portion of the sole; wherein, the padded portion of the heel strap is folded in half to define a pull-tab that extends from the strap channel of sole for a user to grip the pull-tab to release the strap from the strap channel.

In one mode of use, the slip-on footwear is provided to a foot of a wearer, the pull-tab is pulled to expose the heel-strap, the pull-tab is unfolded to define padding for the strap, and strap is placed over the heel of a wearer with the padding provided to the wearer's heel.

In another mode of use, a wearer of the slip-on footwear pulls the padding of the strap off of the user's heel, folds the padding to define the pull tab, and deposits the heel strap in the strap channel of the sole of the slip-on footwear.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Disclosed is slip-on footwear with a concealable heel strap that is padded. Suitably, the padding of the padded heel strap is convertible into a pull-tab whenever the heel strap is concealed. The other specifics of the disclosed slip-on footwear with a concealable heel strap are described with reference to the drawings.

FIG. 1 is a side view of a sandal 1000. FIG. 2 is a front view of the sandal 1000. FIG. 3 is a rear view of the sandal 1000. FIG. 4 is a bottom view of a sandal. FIG. 5 is a top view of a sandal. As shown in FIGS. 1 through 5, the sandal 1000 is comprises a sole 1100, an upper 1200, and a concealed strap 1110 with two pull-tabs 1111.

Still referring to FIGS. 1 through 5, the sole 1100 is best seen in FIGS. 1, 2, 3 and 4, the upper is best seen in FIGS. 1, 2, 3, and 5, and the heel strap 1110 is best seen in FIGS. 1 and 3. As shown, the sole 1110 is typically shaped like a human foot and defined by foam, rubber, or some combination thereof. As best seen in FIG. 4, the upper 1200 is provided to a top surface of the sole 1100. In the preferred embodiment, the upper is defined by a toe hole and a foot strap, the upper can be any type of slip-on known to those of skill in the art. As discussed below in connection with FIGS. 1 and 3, a heel strap 1110 is concealed in the sole 1100.

FIG. 6 is an environmental side view of the sandal in an alternate configuration where the heel strap 1110 is revealed. FIG. 7 is an environmental front view of the sandal in the alternate configuration. FIG. 8 is an environmental rear view of the sandal in the alternate configuration. As shown in FIGS. 6 through 8, the sandal 1000 in the alternate configuration comprises the sole 1100 with a strap channel, an upper 1200, and a revealed strap 1110 that has padding 1112.

Still referring to FIGS. 9 through 8, the sole 1100 is best seen in FIGS. 1, 2, 3 and 4, the upper is best seen in FIGS. 1, 2, 3, and 5, and the heel strap 1110 is best seen in FIGS. 1 and 3. As shown, the sole 1110 is still typically shaped like a human foot and features a strap channel 1120 disposed around the periphery of the heel portion of the sole 1100. As shown, a heel strap 1110 is revealed with padding 1112 positioned over a heel of a wearer.

Comparing FIGS. 1 through 5 through FIGS. 6 through 8, the strap 1110 can be concealed in the strap channel 1120 during periods of non-use or else be provided over the heel of a wearer during periods of use. Suitably, pull tab 1111 is accessible at the heel of the sole 1100 so that the strap may be removed from the strap channel 1120. Suitably, the padding 1112 is unfurled from the pull tabs 1111 after the strap 1110 is pulled out of the strap channel 1120. Once unfurled, the padding 1112 may be provided over the heel of a wearer.

FIG. 9 is a side view of a sandal with the optional use heel strap removed. As shown, the sole 1100 may be provided with a hole 1121 so that the strap may be fastened to the slip-on sandal 1000. Suitably, the hole may be provided through the sole 1100 or the sole may be split 1122 and the strap 1110 (not shown in FIG. 10) sandwiched into the strap channel 1120.

FIG. 10 is a schematic of the optional use heel strap 1110. As shown the padding 1112 may be unfurled in an upright position to define a cup-like heel pad. The padding 1112 may be reverse folded (e.g., by somewhat turning the cup-like heel pad inside out) to create at least one pull tab 1111. Suitably, the padding 1112 may feature a bias to a configuration of a heel pad wherein the strap channel defeats the bias to hold the padding in a folded state to expose the pull tabs. See, e.g., FIG. 1. In one embodiment, the strap is made of rubber or other elastomeric materials.
