Types of Running Shoes

Cushioning shoes provide elevated shock absorption and minimal medial (arch side) support. They're best for runners who are mild pronators or supinators. Cushioning shoes are also good for neutral runners during off-pavement runs. Reason: Minor irregularities in surfaces such as dirt roads give feet a little variety from the repetitive, same-spot strikes they typically experience on hard surfaces.

Stability shoes help decelerate basic pronation. They're good for neutral runners or those who exhibit mild to moderate overpronation. They often include a "post" (see Shoe Construction 101, below) in the midsole.

Motion control shoes offer features such as stiffer heels or a design built on straighter lasts to counter overpronation. They're best for runners who exhibit moderate to severe overpronation.

Know Your Feet

Foot size: If you're unsure of your shoe size or if one foot is larger than the other, it's best to have your feet measured at REI or other shoe retailer with a Brannock device. (That's the flat metal tool with sliders that measure the length, width and the toe-to-ball length of the foot.) Whenever possible, try the shoe on to see if it fits. Shoe lasts (which determines shoe sizes, described below) vary by manufacturer and even from one shoe model to another. You may need a half-size or even a full size smaller or larger than you think.

Most men wear a D-width shoe; most women wear a B-width. You don't have to wear a shoe of your gender—the lasts are basically the same. Men: Try a women's shoe if you have a narrow foot. Women: Try a men's shoe if you have a larger or wider foot. If the shoe fits, wear it!

Arch shape: As you get out of the tub, shower or pool, take a look at the footprint you leave on the bathmat or cement. The shape of your footprint will indicate the type of arch you have. Your arch shape affects the way your foot moves as you run. - Cesarzafra.com
