One day, the British inventor, Willie Johnson, chatted with the owner of a shoe factory. The boss is worrying about the slow-moving products and hopes to invent better-selling shoes.
That night, Johnson lay in bed and wondered how to help the shoe factory owner surprise. Inadvertently, he recalled one thing in his childhood: When he was in elementary school, he often walked around to calculate the distance from home to school. He looked at how many steps he took from home to school and then took a step closer. You can calculate the distance.
Thought of this, Johnson's mind suddenly came up with an idea, if you invent a measure of distance, "counter-step shoes", certainly able to sell well.
After careful consideration, Johnson proceeded to dry up. He set up a microcomputer in a pair of specially processed insoles, and a monitor on the upper. Every step taken by the shoe wearer, the distance traveled will be displayed on the upper.
Later, he made further improvements to the "counter-step shoes" and developed a "speed measuring shoe" that can calculate the time, measure the distance, and show how fast a person is running. After being put on the market, "Speedometer Shoes" was deeply loved by elementary and middle school students and athletes and was known as "Magic Shoes." In the first year of listing in Europe and the United States, more than 100,000 pairs were sold.
