Width
Running shoes are most commonly designed for a typical D width fitting, so you must choose a wider or narrower fit if a standard-size running shoe feels too constrictive or loose. Nike and New Balance offer wider running shoes in addition to normal models. Runners with narrow feet can choose from Brooks, Nike and New Balance, all of which offer narrow running shoes.
Foot Type
A low arch or flat foot runner is prone to injuries because she does not have a distinct curve along the inside of the foot. This type of runner is more likely to overpronate--when her foot hits the ground during a run it will roll excessively inwards, and the foot will not properly absorb impact. Stability shoes feature "dual-density" foam along the medial side of the arch to cushion the foot, absorb the shock of each step and prevent unnecessary movement while running. Examples include Mizuno Wave Inspire 6 and New Balance 1224. As of September, 2010, prices range from the mid-$50s to over $100.
Runners with neutral pronation (approximately 20 to 30 percent of all runners) have a different experience when running. A neutral pronator's foot rolls inward normally and is able to properly absorb shock. These runners can wear standard running shoes. Neutral running shoes are available for about $100, but less-expensive brands are available.
Runners with a high-arched foot need a running shoe with a lot of cushioning to support a higher arch. Runners with a high arch cannot properly absorb the shock felt on the feet when running. In other words, the foot does not roll inwards enough to support the impact of running--a condition known as underpronation. Runners with underpronation require motion-control shoes such as Brooks Beast 10, Saucony Progrid Stabil CS and Asics Evolution 4, which are designed with extra arch support. Motion-control shoes are typically stiffer than other shoe types, so test for comfort before purchasing. Motion-control shoes are available for less than $100; cheaper brands are also available.
Weight
Finding the best running shoe requires some consideration of your weight. Runners with a heavier frame should opt for shoes like the Brooks Beast and Asics Gel Koji, which offer extra cushioning and added support.
Running Surface
Not all running shoes are designed for every surface. Asics Gel Kayano and Mizuno Wave Rider are designed for running on tracks, whereas Nike Air Pegasus and Saucony Jazz 6000 are suited for both on- and off-road running. When choosing the best road running shoes, opt for a shoe with a shallow tread on a long-lasting sole, according to Momentum Sports. Runners hitting footpaths with uneven surfaces will fare better with running shoes that have a deeper tread and lots of traction.
