ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to footwear that may be donned and removed with minimum effort. More particularly, the invention relates to side entry footwear in which the foot enters and exits laterally through a side opening in the footwear.
2. Description of Related Art
Footwear can generally be divided into two categories: those with fasteners and those without. Footwear with fasteners typically require manual fastening. This means bending over, reaching for the feet, and fastening (whether it be laces, Velcro, buckles, or other closures) using rather precise motor skills. There are generally two types of footwear without fasteners: “slip-on” footwear and other footwear that uses elastic material to hold the foot in place. Slip-on footwear usually does not require any fastening, but may not hold the foot well. Footwear employing elastic material to hold the foot in place often requires the wearer to bend down and manually pull on the footwear using force.
Due to physical limitations or simply a desire for footwear that is easier to don or remove, individuals might prefer a shoe with a nontraditional design. For example, the elderly might suffer from common conditions such as arthritis, osteoporosis, deterioration of eyesight, and loss of flexibility of tendons and muscles. Neural problems resulting from diabetes (also common among elderly) and hip replacements add to conditions that make donning traditional footwear difficult.
Existing footwear often is not fitted for use by the elderly. “Slip-on” shoes, though common and practical, might not provide the traction or structural support needed to prevent falls. Donning other types of shoes is often so difficult that the elderly may opt not to use shoes at all. In some cases, the traction afforded by bare and feeble feet might pose more of a risk than wearing a loose fitting pair of slip-on shoes. Among the elderly, accidents are not only a cause for lack of independence, but are also a common cause of death. Of these accidents, many are associated with falls in the home.
SUMMARY OF A FEW ASPECTS OF THE INVENTION
The invention may include footwear having a sole with a toe region, a heel region, and first and second opposing lateral sides. An upper may be connected to the sole along at least a portion of the first lateral side and may be disconnected from the sole in an opening region along at least a portion of the second lateral side. A resilient foot holder is at least partially disconnected from the second side of the sole at the opening region to thereby permit lateral foot entry through the opening region. The foot holder may exert a holding force on the foot to help prevent the foot from slipping out of the opening region during walking. The foot holder may deform to permit the foot to slip out through the opening region in response to a lateral foot motion. While the resilient foot holder may be connected or disconnected from the sole, in a preferred embodiment it is connected to the sole along a first side of the sole.
The footwear may include at least one protrusion extending from the sole. The protrusion is configured to engage another protrusion on an opposite foot of a wearer, to thereby assist the wearer in removing the footwear.
In addition to the foot holder, the footwear may also include a heel holder to cooperate in preventing the foot from slipping out of the opening region during walking. One or more of the heel holder and the foot holder may include a curved surface such as a flipped-back lip for guiding the foot into the opening region. The flipped-back lip may be in the form of a loop and may have an outer radius that is greater than an inner radius. The foot holder may be curved to generally conform to a metatarsal portion of the foot. One or more of the foot holder and the heel holder may be made of a semi-rigid resilient material capable of deforming during entry and egress of a foot.
The sole may include a peripheral ridge for at least partially surrounding the foot to assist in preventing the foot from slipping out of the opening region during walking. The sole may further include texture on a foot contacting surface. The texture may be oriented to make it easier for the foot to slip into the opening region than for the foot to exit the opening region.
While the footwear may have particular benefit for the elderly and those with physical limitations, the invention in its broadest sense is not so limited. It may be configured for use by those without physical constraints, but who desire an alternative approach to footwear. Thus, the invention can be used in slippers, or in any other appropriate footwear product.
Other aspects of the invention will be evident from the description of preferred embodiments and the brief description of the drawings that follow. The following drawings constitute a part of the specification, and together with the Description of Preferred Embodiments, exemplify aspects and principals of the invention.
