1. An electronic marker stake system for locating reference points in a field to be used for multiple sports, comprising:
a first set of marker stakes adapted to be placed in the ground and removably receive first field boundary indicators, wherein said first set of marker stakes emit a first signal associated with a first field sport; and
a second set of marker stakes adapted to be placed in the ground and removably receive second field boundary indicators, wherein said second set of marker stakes emit a second signal associated with a second field sport, and at least one of said first and second sets of marker stakes have individually assigned identification numbers which indicate a sequence that defines a field boundary.
2. The electronic marker stake system of claim 1, further comprising an electronic locator which selectively detects either of the first signal and the second signal.
3. The electronic marker stake system of claim 1 wherein said first and second sets of marker stakes have passive electronic markers.
4. The electronic marker stake system of claim 3 wherein:
passive electronic markers in said first set of marker stakes are tuned to a first frequency associated with the first field sport; and
passive electronic markers in said second set of marker stakes are tuned to a second frequency associated with the second field sport.
The claims below are in addition to those above.
All refrences to claims which appear below refer to the numbering after this setence.
1. A shoe structure for correcting or preventing hallex ectropion and covering toes in the shoe structure, characterized by comprising at least a toe separator, wherein the toe separator is parallel to a wearing direction and is arranged at the internal front end of the shoe structure, and the front end of the shoe structure is divided into a first wearing space and at least one second wearing space.
2. The shoe structure according to claim 1, wherein an externally layer is formed by extending at least one inner surface of the shoe structure from the toe separator, and the toe separator is located in the external layer.
3. The shoe structure according to claim 2, wherein the inner surface of the external layer is either provided with punctiform bulges or covered with a breathable cloth or the combination thereof.
4. The shoe structure according to claim 2, wherein the external layer is connected in the shoe structure in a sewing way.
5. The shoe structure according to claim 2, wherein the external layer is connected in the shoe structure in an interference fit way.
6. The shoe structure according to claim 2 or 3 or 4 or 5, wherein at least a gap is formed in the surface of the external layer.
7. The shoe structure according to claim 6, wherein each gap is set to correspond to the corresponding toe separator.
8. The shoe structure according to claim 7, wherein the toe separators are arranged plurally, and the front end of the shoe structure is divided into a first wearing space and a plurality of second wearing space for separating toes.
