The present invention relates to a multifunctional shoe which includes a shoe, a locating part, a sliding device and a locking device. The shoe has a sole provided with at least an accommodation. The locating part is fixed by a fixing member inside the accommodation and is a hollow body with the opening thereof is directed downward, thereby forming a mounting opening at the bottom of the sole. The sliding device contains a wheel and a wheel base. The wheel base corresponds to the locating part in form so that it can be received in the locating part. The locking device is located at the side of the locating part. A lock pin is disposed inside the locking device and is controllable from the outside of the sole to be axially moved. The sliding device is fixed inside the locking device while the small part of the wheel projects from the sole for sliding purpose; moreover, the sliding device can be stored or disassembled without projection on the sole for walking purpose.

A method according to claim 1, wherein the lower yarn transfer mechanism is an initial winding guide which brings the yarn controlled by the upper yarn transfer mechanism and the yarn passage control mechanism into contact with the peripheral surface of the empty bobbin, shifts it in the axial direction of the empty bobbin and lets the yarn holding portion hold the yarn. 3. A method according to claim 1 or 2, wherein the length of a yarn tail, would after the yarn held by the yarn holding portion begins to be wound around the surface of the yarn winding bobbin until the yarn moving toward the center of the regular traverse area goes into the regular traverse area, is controlled at 10 cm to 200 cm. 4. A method for winding synthetic fibers, according to claim 1, wherein the length of the yarn tail is controlled by a resistance guide kept in contact with the yarn to produce a frictional resistance when the yarn is moved toward the center of the regular traverse area. 5. A method according to claim 4, wherein the resistance guide is a traverse control guide provided at a position opposite to a rotary vane used in the traverse device in reference to the traverse yarn passage defined by the traverse device provided as a rotary vane mechanism. 6. A method according to claim 4, wherein the resistance guide is a yarn disengaging guide for disengaging the yarn from the traverse guide in a direction perpendicular to the traverse direction at the time of yarn transfer from bobbin to bobbin. 7. A method according to claim 4, wherein a combination of at least two or more resistance guides is used instead of the resistance guide. 8. A method according to claim 4 or 7, wherein the length of the yarn tail is finely adjusted by adjusting the position of at least one of the resistance guides. 9. A method according to claim 4, wherein the length of the yarn tail is finely adjusted by adjusting the position of the traverse fulcrum guide. 10. A method according to claim 1, wherein when the yarn is moved toward the center of the regular traverse area, the yarn is supported by a threaded groove to control the length of the yarn tail by the rotation of the threaded groove. 11. A method according to claim 10, wherein the threaded groove is formed in the surface of the contact pressure roller. 12. A method according to claim 1 or 2, wherein the yarn holding portion is a slit extending in the circumferential direction in the surface at an end of the yarn winding bobbin. 13. A method according to claim 1 or 2, wherein the yarn holding portion is formed at a border between adjacent yarn winding bobbins. 14. A method according to claim 1 or 2, wherein the yarn holding portion is formed by the border between an end of a yarn winding bobbin and a tubular member. 15. A method according to claim 1 or 2, wherein a position where the yarn is disengaged from the yarn keep guide immediately after the yarn has been held by the yarn holding portion is on a non-traverse side in reference to the yarn holding portion, viewed in a direction perpendicular to the spindle axis. 16. A method according to claim 1 or 2, wherein the surface bunch of the wound yarn package is formed at least 5 mm or more inside from an end of the yarn wound package. 17. A yarn winding apparatus in which a yarn is wound around an empty bobbin comprising: a) a traverse fulcrum guide for winding the yarn; b) a traverse device for trave
