And, you'll not only jump, but get some relief for your feet, knees, and back. The spring comes from a real spring attached to the heel of the strange, space-age shoe that Al Gallegos wants to sell you. He's the 73-year-old inventor of the Z-CoiL line of pain-relief footwear (鞋类), which, he says, "will surely bring a smile to your face ." The spring functions as extra cushioning to help prevent foot problems. A total of 350,000 pairs of these shoes have already been sold. Z-CoiLs first hit the shelves four years ago in New Mexico, US. Since then, the shoes have become the rage. They're only sold through authorized dealers, and target people with painful leg, foot and back problems. No need to worry about some popular sportswear companies, at least for now. "It's a dream coming true after such a long time and so much work," says Gallegos. He first thought of using springs in shoes while out running his typical seven miles one day. His thought was this: Every car, from economy to luxury vehicle, uses shock absorbers (减震器) to take the rough road bumps while passengers sit smoothly in their seats. Why not use the same simple technology in footwear? "When I made my first Z-CoiLs, I knew people would like the idea. But I didn't think people would take to them the way they have. Now I just want to get a shoe on the next person and make them feel good," says Gallegos. The shoes are funny-looking. But they come in different styles. And they do make you bounce. Surprisingly, the shoes aren't advertised; they are sold by word-of-mouth and dealers will often go to hospital and medical conventions to demonstrate the shoes for potential customers. They are priced at roughly US75-100, depending on the style. It's estimated that 75 percent of people experience some kinds of foot health problems at one time or another in their lives. Gallegos says the footwear helps them and those suffering from lower back pain, arthritis (关节炎) and knee problems.1.
