Whether you\'re jogging, walking, or just trying to look good while kicking, running shoes can be expensive. According to marketing firm Statista, the average cost of running shoes increased by 21% from 2007 to 2014. Traveling to the sporting goods store can make you $85, $110 or $260, but there are also cheaper options. I visited department stores, supermarkets and online shoe stores and found four options under $50. Question: can you run comfortably in less than $50 shoes? $49 Skechers GOrun 4 $44 Reebok Twistform Blaze $34 Champion C9 legend $14 sports technology running shoes. I shipped three pairs of each pair to the bioengineering lab in Portland, Oregon. Martyn Shorten. Dr. Shorten created a series of tests for manufacturers and runner guides to evaluate running shoes. He first put his shoes on a device that can measure the buffer. He then uses another machine to quantify the flexibility. He cut the shoes in half, checked the internal structure, and finally used the test runner in the motion capture suit to analyze how each pair of shoes affected the gait and physical movement. We decided to ask the doctor. Analyze each pair and then I run in sneakers to assess how they feel about me personally. Before we get into each brand, here\'s what I got from Dr. Shorter about buying cheap running shoes. 1) The best investment you can make in running is to analyze your gait. Go to a business store and let them see how you run it. Do you pronate? Do you run with your front foot? Mid-foot? Are you a heel/toe runner? Dr. Once you know if you have any specific questions ( Pronunciation is the most common) , You can buy shoes for the specific address you need. But if you have a standard gait, he says any comfortable shoes should work. What makes shoes comfortable? Dr. Shorten broke it down. \"Make sure you have some wiggle room on your toes, run around it, and don\'t walk around the store,\" he explains . \". \"It should feel really good, no friction, no friction. It should not be the same weight as the bottom of your foot. If you don\'t feel it, it might be good for you if you don\'t notice it\'s there. ”2) There is no shelf life for running shoes. Use them until they start to disintegrate or lose buff/comfort. 3) It is OK to buy last year\'s model. Running shoes do not expire according to age and only need to be replaced after long use. 4) The same rule applies if your child does not have an obvious gait problem; If the cheaper shoes are comfortable Short said it would not hurt to wear them. 5) In his research Shorten asked thousands of people identified as runners how many miles they ran each week. The median is 8 miles. If you want to buy top-of-the-line engineering running shoes for these 8 miles, that\'s great, but don\'t make costs a barrier to entry. Many guides and writing-High-ups End shoes is designed for those who log in more than 8 miles a week and get more technical needs from their shoes. The $49 Skechers GoRunThis shoe scored the highest in all quantitative tests of cushioning, stability and support. Dr. The shoes, added Shorten, are \"very light, flexible and have a good buffer. Skechers has achieved some real success in running shoes. A different shoe in the Skechers GOrun series makes it the best guide for runners in the world in 2016. The shoes for $49 feel great. It is very light and has a lot of arch support. $44 Reebok TwistForm BlazeI likes the look of these shoes and is comfortable to walk; They were second in the buffer test. Dr. However, Shorten points out some negative effects. \"I\'m a little worried that it has this kind of thick soft stuff -- \"The only memory foam and other buffer materials are not much,\" he said . \". \"It will feel comfortable in the store, but once you run on the street it will flatten and the shoes will feel harder to wear. \"When I run with my shoes, the memory foam is not very suitable for me because when I run, my feet feel like walking around the shoes. We contacted Reebok and they said, \"all Reebok running shoes are designed to meet specific consumer needs and we thoroughly tested our technology to achieve high standards. Memory Technology is a comfort technology that has been designed and tested to improve comfort for our consumers. The midsole foam we use in the TwistForm shoes discussed works in conjunction with sockliner and the overall shoes to provide the ideal running experience. In addition to memory technology, we also have a soft cushion technology called memory technology massage, which provides comfort and flexibility. At present, we use this product in products with higher prices, but plan to bring this experience to more products in the future. \"The $34 Champion C9 legendary running shoes look good and feel strong when you wear them. Its test results did not beat skic\'s shoes, but Dr. Shortened like a building. \"It has a good upper, some good padding around the ankle, and a good tongue,\" he said . \". But when I was running in these clothes, my unique running style caused some friction and pressure at the end of the shoe lace because I bent my feet to push it away. Running shoes for Althletech ($14) Kmart house brand)Dr. Shorten pointed out that these shoes are not the same as the other shoes in our sample -- The building on the front foot. \"I saw some old-fashioned techniques and I basically saw the overlay that was fixed with the stitching,\" he said . \". When I walk in my shoes and when my feet bend I do feel a little split. Another factor Durability is pointed out. \"I see a single piece sole with no rubber outside, which means it won\'t be very durable,\" he explains . \". But Althletech shoes scored very well in the stability test Shorten did it, second only to Skechers in terms of stability. When I took out my shoes on the road, I was pleasantly surprised --- They provide a lot of buffering and support. I like them because it is running shoes second only to Skechers. We contacted Sears/kemat, who said in a statement: \"There are a wide range of running shoes. Athletech Dash is designed for an increasingly active and leisure lifestyle, not as high End running shoes. Athletech Dash is highly rated by our members and is worth less than $20.
