A shoe assembly comprising, in combination:
- a lower shoe portion adapted to cover a lower portion of the foot of the wearer, said lower shoe portion including an elongated sole, a heel at one end of said sole and a curved toe at the opposite end thereof and having an elongated upper edge portion extending around said heel starting at a point located adjacent to said toe on one side of said lower shoe portion and ending at a point located adjacent to said toe on the opposite side of said lower shoe portion;
- an upper shoe portion adapted to cover an upper portion of the wearer's foot, said upper shoe portion having an elongated lower edge portion the length of which is substantially equal to the length of said upper edge portion, said upper shoe portion being of a size and shape such that it defines an elongated opening extending substantially between said toe and said heel for receiving the foot of said wearer;
- and
- means for releasable connecting said lower edge portion to said upper edge portion so as to leave an open throat between said starting and ending points whereby said upper and lower shoe portions can be easily attached to and detached from one another during use of said shoe assembly.
