Definitions

  • Footwear that covers a user's ankles are typically either of the slip-on type or are of the type that includes mechanisms that are tightened to hold the boot securely against the foot during use and loosened to facilitate foot entry and exit from the boot.
  • Slip-on boots can be quicker and easier to take on and off than boots with tightening mechanisms that are loosened and tightened for foot exit and entry.
  • the inner volume of slip-on boots is often substantially larger than the volume of the foot that the boot is intended to fit.
  • the relative large inner volume of such boots can result in a poor fit, as the user's foot can substantially slide around in the boot during use.
  • the present disclosure provides a slip-on boot with fit features that enable an improved fit while still allowing for convenient foot entry and exit from the boot. Related methods of using and manufacturing a slip-on boot are also provided.
  • FIG. 1 is a side view of a footwear according to the principles of the present disclosure
  • FIG. 2 is a back view of the footwear of FIG. 1 ;
  • FIG. 3 is a cross-sectional view of the footwear of FIG. 1 along line 3 - 3 of FIG. 2 ;

  • FIG. 13 is a side view of the last of FIG. 11 with the heal portion slid away from the main body portion;
  • FIGS. 14 and 15 are side views of a footwear partially removed from the last of FIG. 12 ;
  • FIG. 16 is a side view of the last of FIG. 16 with a slip sheet.
  • the footwear is a slip-on boot where the foot fitting volume (the inner volume of the boot) is not as highly adjustable as compared to boots that have laces configured to be loosened to allow foot entry/exit and tightened to secure the boot onto the user's foot.
  • the shape and size of the inner volume of the slip-on boot approximates the shape and size of the user's foot.
  • the close approximation results in a fit that helps secure the user's foot in the boot 10 .
  • the foot fitting volume of the foot fitting portion of the boots is significantly larger than the foot that the boot is designed to fit. The large difference between the volumes is provided for clearance that is typically provided for foot entry and exit from the slip-on boot. Referring to FIG. 11 , a prior art slip-on boot configuration is shown.

  • the broken line labeled 302 represents the silhouette of the user foot and lower leg in an intermediate position in the boot (moving into or out of the boot).
  • Such prior art slip-on boot configurations result in an undesirable sloppy fit (e.g., the user's foot substantially moves around within the boot during use, the user's heel sliding up and down within the boot during use).
  • the boot 10 is configured to press against the user's foot 30 to prevent the foot from inadvertently pulling out of the boot during use.
  • the boot 10 presses back against the heel and instep of the user's foot when the user raises his or her foot, thereby holding the foot 30 securely within the boot 10 as the user walks. See FIG. 5 illustrating that the boot 10 according to the depicted embodiment is configured to hold down at least the user's heel 32 and instep 34 when the user raises his or her foot, as when he or she takes a step.
  • the boot 10 does not need to apply constant downward pressure on the user's foot in order for the fit feature to function.
  • the boot 10 of the present disclosure does not need to impinge on the user's foot in order to stay secured to the user's foot.
  • the boot of the depicted embodiment provides for some clearance between the users foot and the boot to avoid the user's clothing (pant leg, sock, etc.) from bunching.
  • the boot could be configured to apply constant pressure on the user's foot.

  • the air can be provided through the last itself via one or more air channels that are internal or external to the last. As discussed above, the air flow channels/apertures can be located in particular areas of the last. Alternatively, the air can be provided to a singular location in the last (e.g., the toe end 214 of the last).
  • the air can be trapped between the last and the inner surface of the footwear by sealing the upper portion of the footwear against the upper portion of the last.
  • the seal can be created by pressing the upper of the footwear against the last or by folding over the upper portion of the footwear to form a seal between the upper portion of the footwear and the last. While the footwear is inflated the footwear can be slid part way off the last.
