Expandable shoe and shoe assemblies

Abstract

An improved expandable footwear and inner assembly are disclosed. The footwear has a foot dressing, an adjustable inner assembly disposed within the foot dressing and a stiff member. The adjustable inner assembly has two outwardly extending members, and the stiff member has a channel to nestle the two outwardly extending members to resist undesirable rotation of the inner assembly. The inner assembly has a control for controlling the dimension of the footwear which includes a concave-shaped urging member, that when depressed, allows the footwear to expand or contract, and when not depressed, prohibits such movement.

1 . Footwear, comprising: 
 a foot dressing;    an adjustable inner assembly, disposed within the foot dressing, and having at least one outwardly extending control member; and    a stabilizing member having a channel adapted to receive the at least one outwardly extending control member to resist rotation of the inner assembly.    
     
     
         2 . The footwear of  claim 1  wherein the inner assembly has two outwardly extending control members and the channel is adapted to receive the two outwardly extending members.  
     
     
         3 . The footwear of  claim 1  wherein the foot dressing has an upper foot portion and a sole portion and the stabilizing member is in contact with the upper foot portion and the sole portion.  
     
     
         4 . The footwear of  claim 1  wherein the foot dressing has a toe portion and a heel portion and the stabilizing member is in the heel portion.  
     
     
         5 . The footwear of  claim 1  wherein the stabilizing member is a midsole.  
     
     
         6 . The footwear of  claim 1  wherein the channel is U-shaped and the at least one outwardly extending control member is cylindrical.  
     
     
         7 . The footwear of  claim 1  further comprising a rod extending through the at least one outwardly extending control member.  
     
     
         8 . Footwear comprising: 
 a foot dressing and    an adjustable assembly, at least a portion of which is coupled to the foot dressing, the adjustable assembly having a first member and a second member in overlapping engagement with each other and a control integral to the footwear to adjust the position of the first member relative to the second member and to thereby adjust a dimension of the adjustable assembly and thereby a corresponding dimension of the footwear, the control having a manually depressible concave-shaped member that, when depressed allows the first and second members to be moved relative to each other and when not depressed, inhibits such movement.    
     
     
         9 . Footwear, comprising: 
 a foot dressing; and    an adjustable assembly, in contact with the foot dressing, the adjustable assembly having a first member and a second member, each shaped for relative movement with respect to the other; and a manual adjustment assembly having a concave shaped portion thereof manually accessible from the foot dressing and another portion thereof engageable with an engagement member fixed to one of the first and second members, wherein the engagement member is translationally urgable to at least one of two states, in which a first state allows the first and second members to be moved relative to each other to adjust a dimension of the footwear and wherein the second state inhibits such movement.
