Dash across the road, the sidewalk, cobblestones, and whatever else you find in your way around your city, town, or back roads. Road running is a fun, easy way to get into running no wherever you live. Running shoes are divided into four categories that describe how the shoe supports the roll of your foot when it strikes the ground (how it pronates): neutral, motion control, stability, and minimalist. Keep in mind that fit varies from brand to brand and shoe model to shoe model and avoid buying shoes based on looks alone (or even mostly the looks).
How you pronate dictates the general type of shoe you need: low arch/normal pronators should look for a stability shoe, flat arch/overpronators with excessive inward roll need a motion control shoe or stability shoe, and high arch/supinators (or underpronaters) should look for a neutral shoe.
Drop is a measurement of the difference in ground-to-heel and ground-to-toe height between your heel and your toe. High drop shoes will ramp your foot forward while low drop (or zero drop) shoes bring your heel and your toe level.
