Abstract

The inventive subject matter is generally directed to dance shoes that include a distal portion for receiving at least a portion of a forefoot of a wearer. The distal portion includes a rigid structure for supporting the foot, such as a toe box for an en pointe dance shoe. A proximal portion extends from the distal portion and it is configured for receiving the midfoot and rearfoot portions of the foot. The shoe is constructed so as to conform to the shape of the foot through a range of foot flexations that vary the distance of the toes to the heel, particularly the flexations that occur when dancing en pointe. According to certain embodiments of the inventive subject matter, this is achieved in whole or part by configuring the proximal portion to be elastically, longitudinally extendible relative to the distal portion and/or configuring the shoe's foot-receiving compartment with a shape that generally mimics the foot in a shape corresponding to plantar flexation, for example, a shape mimicking a foot en pointe.

Technical field

Present subject matter relates in general to a kind of dancing shoe, and it comprises the distal part of the part of the front foot at least receiving wearer.Distal part comprises for supporting sufficient rigid structure, such as, for the toe-cap of full toe dancing shoe.Portions of proximal distally part extends, and is configured to the mesopodium and the hindfoot portions that receive foot.Footwear are configured to the shape adaptation of the foot flexible with the foot through certain limit, and the flexible change toe of foot is to the distance of following, and what particularly occur when full toe is danced is flexible.Some embodiments according to the inventive subject matter, this can realize in whole or in part in the following manner, namely make portions of proximal be configured to relative to distal part elasticity, can be extending longitudinally and/or the foot of footwear is received compart-ment constructions and have the shape of foot when imitating full toe.

Background technology

Ballet dancer uses the toe footwear of particular design to help dancer and stands with its toe point, is called that " full toe " dances.Toe footwear are usually by being that the foot of dancer provides supporting with lower component, i.e. (1) toe-cap, the rigid structure of other parts some or all of of and front foot anterior as encapsulating toe, and (2) footwear core pad, it is therefrom extending longitudinally.Toe-cap surrounds foot through metatarsal usually, and the sidepiece of dancer's foot is held in place.Footwear core pad is elongated rigid member, it is structurally connected to (such as independent attachment or as integral piece) toe-cap, and extends back from toe-cap, in the bottom of footwear, sufficient supporting part, usually at least through the midfoot area of footwear to hindfoot areas.

When full toe is danced, footwear core pad and toe-cap help supporting foot, the weight of dancer and help distributes on the foot of wider area, instead of weight is concentrated on toe.But in order to distributed weight effectively, footwear should closely be coupled on the foot of dancer.

A problem of tradition toe footwear is sufficient size moves (namely how the foot of dancer stretches or shrink during dancing) according to position and changes.Such as, when foot keeps flat on the ground, foot is in its form of elongating most (see Fig. 1), is totally filled with the dancing shoe of appropriate size.Dancing shoe be engaged in smoothly in the length and width of foot sufficient around, and there is no redundant space in the hindfoot portions of dancing shoe.But the foot of full standing on tiptoe takes more arc shape, shorten toe point and the distance between following, and footwear no longer closely cooperate.Therefore, the traditional dance being placed in full toe position becomes sagging and gauffer (see Fig. 2) in midfoot or hindfoot portions.

Foot in ballet, modern dance and other dancing forms attractive in appearance most important.Unfortunately, until present subject matter described herein, also do not have enough solutions to provide the footwear of suitably supporting, it keeps outward appearance that is level and smooth and not gauffer, naturally fits through the flexible foot of the foot of certain limit.

Another FAQs of tradition toe footwear is their too rigidity in the midfoot of dancing shoe usually.Therefore, dancer needs break-in footwear to obtain to wish flexibility.Break-in dancing shoe generally includes fully that bending hard footwear core pad is to form the platform for following, and slightly softening toe-cap bends when half toe to allow footwear sometimes.Due to this manipulation, toe-cap and/or the footwear core pad of toe footwear can die down, and easily demote, and make footwear be unable to undergo to use.

The one manufacturing more flexible toe footwear is attempted in U.S. Patent No. 6, and 895, describe in 693, which depict one " composite base " footwear, in mesopodium, namely there is no the footwear of soling materials.(' 693 patent here merge therewith for all objects are overall by reference).Although this patent describes the progress in toe footwear flexibility, this footwear have undesirable sagging and gauffer when footwear are placed in full toe position.

Therefore, need a kind of toe footwear and other dancing shoes to support foot, the foot of flexible with the foot through certain limit (comprise with full toe position corresponding those) is adaptive simultaneously.Also need a kind of full toe and similar footwear, it provides larger flexibility, eliminates or reduce wearer to manipulate toe-cap or footwear core pad to realize expecting the needs of cooperation.

Summary of the invention
