I want to introduct something about SOFT EXPANDER. Model No: SCE01P(7x10) SOFT EXPANDER Description: *SIZE: 7x10x1000mm *1PC/DOUBLE BLISTER(60PCS/CTN) *SIZE: 52x28x41CM Boardsports are sports that are played with some sort of board as the primary equipment. Surfing, first mastered in the Pacific islands, was the first board sport. Eventually, it was expanded to land applications, often with the addition of wheels. Many board sports are classified as action sports or extreme sports, and thus often appeal to youth. Board sports have had a history of being dangerous, "punk" or reckless, and thus were marginalized in the sports community. However, many board sports have gained mainstream recognition, and with this recognition have enjoyed wider broadcast, sponsorship and inclusion in institutional sporting events, including the Olympic Games. Surfing was the first boardsport, or the mother of the other boardsports, originating from the Polynesian culture. Skateboarding was then invented by surfing looking to "surf" on land. Snowboarding came around when surfers and skaters were looking to board on the snow. Wakeboarding was invented by people so that they could get towed in snowboard fashion behind a boat in the same relation as waterskiing to alpine skiing. Mountainboarding was then invented by snowboarders who wanted to keep riding on the piste even after the snow had gone. One can calculate, using estimations for the numbers participating in certain individual boardsports (30 million skaters, 25 million surfers and 15 million snowboaders), that there are approximately 100 million people participating in these sports. That is if you do not take into consideration people doing more than one of these sports each, which of course, in reality, is highly likely.

Windsurfing Also known as sailboarding. A water sport involving travel over water on a small 2-4.7 meter board powered by wind acting on a single sail. The sail is connected to the board by a flexible joint Bodyboarding Wave riding consisting of a small, roughly rectangular piece of foam, shaped to a hydrodynamic form. The bodyboard is ridden predominantly lying down, (or 'prone'). It can also be ridden in a half-standing stance (known as 'dropknee') or can even be ridden standing up. Wakeboarding A surface watersport created from a combination of water skiing, snow boarding and surfing techniques. As in water skiing, the rider is towed behind a boat, or a cable skiing setup. Skurfing Another fast growing boardsport is skurfing a mix of surfing and more conventional water sports in which the participant is towed behind the boat. Kneeboarding A discipline of surfing where the rider paddles on his belly into a wave on a kneeboard, then rides the wave face typically on both knees. Kiteboarding Involves using a power kite to pull a small surfboard, or wakeboard on water. Other variations are to use a wheeled board or buggy on land, or skis or a snowboard on snow. Skimboarding A discipline of surfing involving riding a board on wet sand or shallow water. Not usually competitive, it is considered a miscellaneous beach recreation activity. Riverboarding A boardsport in which the participant is prone on the board with fins on his/her feet for propulsion and steering Flowboarding Similar to surfing but done on a man-made artificial sheet wave. Land Skateboarding Uses a board mounted on wheels, and often ridden on a "half-pipe" or in urban settings. Some of the most famous skateboarders, and early pioneers of the sport are Rodney Mullen and Tony Hawk. Streetboarding Similar to a skateboarding, but also influenced heavily by snowboarding. Mountainboarding Similar to snowboarding, but on snow-less peaks (in between winter seasons). The board is wider and sturdier. Mountainboarding is similar to skateboarding in the way that mountainbiking is similar to regular biking. Kite landboarding Similar to Kite Surfing but the kite is used to pull the rider along flat ground (often a hard packed sandy beach) on a mountainboard. Pineboarding A recreational activity in which a participant rides down the pine-needle-covered slopes of pine forests on a skateboard deck (without trucks or wheels). Rope boarding Uses a board hanging from a rope, ridden by swinging through the air, and landing on elevated platforms of launching off the tree it hangs from. Freebording Often said to be the board who's feel is the most similar to snowboarding.
