A collapsible snowshoe is provided. The snowshoe includes a frame having a first supporting cross-bar configured to interact with a second supporting cross-bar, wherein the cross-bars are configured to alternate between an open position and a closed position, a first supporting material configured to be coupled to the cross-bars and further configured to extend between the cross-bars, whereby the extended supporting material creates a support surface for walking when the cross-bars are in the open position; and a frame-locking mechanism configured to secure the cross-bars in the open position.

1. A method for walking using a snowshoe, having a supporting cross-bar configured to cross and to be pivotally coupled to another supporting cross-bar, wherein the cross-bars are configured to alternate between an open position and a closed position, wherein each said supporting cross-bar and said another supporting cross-bar includes a respective front portion and a respective back portion and said pivotal coupling of said supporting cross-bar and said another supporting cross-bar is configured to be located between respective front and back portions of said supporting cross-bars, a supporting material configured to be coupled to the cross-bars and further configured to extend between the cross-bars, whereby the extended supporting material creates a surface for walking when the cross-bars are in the open position, and a frame-locking mechanism configured to secure the cross-bars in the open position, the method comprising the steps of: extending cross-bars from the closed position to the open position; andsecuring the supporting material to the front portion of the cross-bars using the frame-locking mechanism. 2. The method according to claim 1, wherein the snowshoe includes a shoe holder coupled to a top portion of the first supporting material, the method further comprising: inserting a shoe into the shoe holder for walking. 3. The method according to claim 2, wherein the shoe holder is configured to secure a shoe to said frame. 4. The method according to claim 2, wherein each said cross-bar includes a front portion and a back portion, wherein said front portion is curved upwards. 5. The method according to claim 4, wherein said front portion is curved upwards at an angle of 10° to 90° relative to said back portion. 6. The method according to claim 4, wherein the snowshoe includes a pivot configured to pivotally couple said cross-bars; wherein said cross-bars are configured to rotate about said pivot to a predetermined angle. 7. The method according to claim 4, wherein each said front and back portion is configured to independently rotate around said pivot. 8. The method according to claim 7, wherein a distance between outermost tips of said front portions of said cross-bars, located away from said pivot, is configured to be greater than a distance between outermost tips of said back portions of said cross-bars, located away from said pivot, when said cross-bars are in said open position. 9. The method according to claim 6, wherein said cross-bars are configured to telescopically expand away from said pivot. 10. The method according to claim 6, wherein said first supporting material is configured to be permanently coupled to said back portion of each said cross-bar and, using said frame-locking mechanism, to be detachably coupled to said front portion of each said cross-bar. 11. The method according to claim 10, wherein said first supporting material is configured to be detachably coupled to said front portion of each said cross-bar between said pivot and outermost tips of said front portion of each said cross-bar. 12. The method according to claim 6, wherein a diameter of said cross-bars is in a range of 8 mm to 40 mm;a total surface area of said supporting materials is in a range of 75 square inches to 375 square inches. 13. The method according to claim 6, wherein said first supporting material further comprises two sides, wherein one side is configured to extend between said front portion of said cross-bar and said back portion of said another cross-bar and another side is configured to extend between said front portion of said second cross-bar and said back portion of said cross-bar;a back side configured to extend between each said back portion of said first cross-bars, when said cross-bars are in said open position;wherein each said side is configured to have varying degrees of concavity. 14. The method according to claim 6, wherein the snowshoe includes a second supporting material configured to restrain rotation of said cross-bars about said pivot; wherein said first supporting material further includes a top portion and a bottom portion and said bottom portion of said first supporting material is configured to be adjacent to said pivot and said cross-bars. 15. The method according to claim 14, wherein at least a portion of said first supporting material is configured to be permanently coupled to said back portion of each said cross-bar; andsaid second supporting material is configured to be permanently coupled to said front portion of each said cross-bar. 16. The method according to claim 15, wherein said frame-locking mechanism is configured to be detachably coupled to said front portions of said cross-bars and thereby restrain rotation of said cross-bars from said open position to said closed position. 17. The method according to claim 16, wherein said cross-bars are configured to be substantially apart to each other in said open position and said cross-bars are configured to be substantially adjacent from each other in said closed position. 18. The method according to claim 2, wherein said frame-locking mechanism is configured to be secured to at least a portion of said first supporting material. 19. The method according to claim 2, wherein said cross-bars are manufactured from a material selected from a group consisting of: aluminum, titanium, stainless steel, fiberglass, fiber, wood, steel, magnesium, carbon-fiber, magnesium-lithium alloy, and plastic. 20. The method according to claim 2, wherein said supporting materials are selected from a group consisting of: micro-fiber, nylon, acron, and Kevlar, polyester, polymer, polyethylene, polypropylene, Mylar, silk, and cotton.
