So you have decided to take the plunge and start exercising. But deciding whether you are going to walk or run isn’t the final step to a successful workout. You must understand what type of foot you have in order to maximize your potential. That determines the motion of your foot while running. Not only are sneakers designed for the type of activity you are planning to use them for, but certain styles are better for certain foot types.
THE WET TEST
A simple way to determine the type of foot you have is to take The Wet Test. Dip your foot in water and place it on a piece of paper so you see the imprint of your foot’s shape. Your foot shape should fall into one the 3 categories: normal, flat, or high arch.
TYPE OF FOOT
Normal feet tend to land on the outside of the heel, and then roll inward somewhat to absorb the stress.
Recommended Sneaker Type:
Stability - This type of shoe has a good mixture of durability, support and cushioning. They are considered the middle ground between motion control and stability.
Flat feet land on the outside of the heel, rolling extremely inward to absorb the stress.
Recommended Sneaker Type:
Motion Control - As the name suggests, motion control shoes allow for the least amount of movement. Often the heaviest of the shoes, these sneaks prevent the foot from rolling excessively.
High arched feet do not roll enough to absorb the stress of landing.
Recommend Sneaker Type:
Cushioned - Not only are cushioned shoes the softest, but they also the most flexible -- allowing the greatest range of motion. The softness absorbs the shock on a runner’s body from the foot not rolling.
Along with these three main types of sneakers, there are also lightweight sneakers, designed for racing, and trail sneakers, designed for off-road running.
Sneaker proprietors are beginning to understand the needs of runners. One catalogue in particular, Road Runner Sports, categorizes each of the shoes they sell based on foot types. In fact, they also have an online form you can fill out to further determine the best shoe for you.

SNEAKER BUYING TIPS
Swollen Feet = Better Selection: Go shopping for new sneakers at the end of the day when feet are larger from walking and standing.
Stick with what you know: If you are happy with your current sneaker make and model, consider buying another pair for when the old ones wear out.
Wear is good: Don’t wear brand new shoes if you are running a marathon, or even a good distance. Your feet have to adjust to and shape your new kicks.
Tie 'em Up: When you are lacing up your sneaks before running, make sure they aren’t too tight or too loose. Either one will not only affect your performance, but will hurt your tootsies.
Reaching the Finish Line: Running shoes should be replaced about every 500 miles. That means if you are running 20 miles a week, you should replace your sneakers every 6 months or so.
