The first step of any full or half marathon training should be finding proper support for your feet. Running is a high impact sport. Without the right footwear that fits your feet well, you may injure yourself before you even start your marathon. From blisters to foot strains and sprains, there are a number of obstacles to runners as they train for a marathon. Whether you\u2019re training on a road, trail, or at the gym, it\u2019s important to support your movements and help you avoid injury.\nJonathan Greenawalt, PT, DPT, of UPMC Sports Medicine, offers his suggestions to help you support your perfect pair.\nWhy Wear Running Shoes\nThe demands of distance running require a more specific shoe than you may wear for other athletic activities like cycling, hiking, or court sports. The right shoe can help reduce your likelihood of developing common running injuries such as:\n\nShin splints\nKnee injuries-runner\u2019s knee\nLateral\/patellar injuries\nHamstring injuries\nAchilles tendonitis\nLow back pain\n\nHow to Find Running Shoes\nThe key to finding your perfect running shoe and kick starting your marathon training is to know your feet. Different styles of shoes are recommended depending on your gait, which includes factors like your arch, motion mechanics, and the part of your foot that strikes the surface on your run (heel, toe, mid-foot, etc).\nMany of the major running shoe brands, as well as running information groups, offer online evaluations. These questionnaires begin with basic questions like height, weight, age, and gender, but lead to more specific gait questions. Some runners, especially new ones, may be unfamiliar with these terms and therefore unable to fully utilize these resources. To get you ready for your marathon training, read on for our breakdown of these running-specific shoe-fit terms.\nConsider investing in sport-specific shoes if you practice three or more times a week! #marathon Click To Tweet\nRunner\u2019s Gait\nA runner\u2019s gait refers to a runner\u2019s style. It is a common misconception that a gait analysis only involves your feet. In actuality, gait depends on your individual foot, running preferences, and training frequency. It is determined by a holistic view of your running movement. Prior to choosing a new running shoe, consider a professional gait analysis from a licensed shoe-fitter or retailer.\nGait analysis can help you identify your arch, motion mechanics, and what type of striker you are, which all play important roles in running. Types of gait analyses vary by retailer but can involve computerized software to film your running style and measure your feet.\nThere are also a number of at-home gait analyses focused on particular characteristics which can help you learn more about your feet prior to figuring out what shoes to buy.\nArch\nThe foot\u2019s arch is the anatomy of your foot\u2019s bones and tendons which support the body. Arches are broken down into:\n\nNormal\nFlat\nHigh\n\nThe wet test helps identify your arch type by marking where your foot contacts the ground. Simply wet your left foot and step on a brown piece of paper. Examine the water mark to learn about the positioning of your foot.\n\nNormal- If your footprint shows a curve on the inside.\nFlat- If you see the full sole of your foot with little curve on the inside.\nHigh- If the mark shows a dramatic curve on the inside, almost connecting the ball of your foot and heel with a thin line.\n\nIf using your right foot for the wet test, the above characteristics will be reversed. For example, a normal arch will show a curve on the outside of your footprint.\n\nMotion mechanics\nMotion mechanics are measured by pronation, or the inward movement of the foot, which also can be tied to arch type. Pronation occurs when the feet roll toward to the inside while running. Pronation is normal, but cases of over and under pronation can leave runners susceptible to injury and may require additional cushioning and support. Under pronation is known as supination and causes the feet to roll to the outside. When cushioned and supported with running shoes, these motion mechanics don\u2019t have to inhibit your training.\nA simple way to determine your level of pronation is to look at your shoes for areas of wear. If the inside or outside of your left shoes are worn down, you may run with under or over pronation respectively. For your right foot, wear on the inside of your shoes may indicate over pronation while wear on the outside can indicate under pronation.\nSome shoe fitters recognize a correlation in arch type and types of pronation. Because of this, the wet test can be helpful for some runners to identify pronation. Generally, the following arch types are associated with pronation type:\n\nNormal arch-normal pronation\nhigh arch- under pronation (supination)\nflat arch-over pronation\n\nStriker\nYour striker refers to the area of your foot that hits the ground in your stride. Most runners have strikers in one of the following regions of the foot:\n\nForefoot\nMidfoot\nHeel\nExtreme Heel\n\nAdditional shoe padding around your striker can reduce injuries, cushion your feet, and reduce some of the pain and strain from the impact of your stride.\nHow to Get the Right Fit for Running Shoes\nMost specialty store employees are trained to help you select the best shoe for your foot. Based on your gait and other influencing factors, these employees can help you try on a variety of running shoes to find your perfect pair. As you browse, look for styles with additional cushioning around the areas where your feet need support. Always try on shoes while you are wearing the type of sock you plan to run in.\nRemember that running shoes should offer a snug but not tight fit. Leave 3\/8 to 1\/2 inch, or roughly a thumb\u2019s width, between your longest toe and the front of the shoe. Your heel should rest on a supportive back but not feel forced or pressed. Be sure to take a practice jog around the store to make sure these requirements are met with movement.\nRunning shoes should be replaced with wear. Experts suggest every 6 months or 600 miles. If you\u2019re considering a new pair of shoes, be sure to give yourself ample time to break them in based on your preference.\nIf you\u2019re training for a marathon, schedule an appointment to make sure you\u2019re in peak physical condition as you take off for the finish line.
