When the arch of the foot is inadequately curved, it is known to be “fallen.” If there is no arch at all, a person has “flat feet.” A foot’s arch is a natural shock absorber for the body, easing any trauma from harsh jolts.
Runners with flat feet will need shoes with peak reinforcements. “Stability Running Shoes” is the advertising term used for the type of shoe that has been designed with this extra support.
A well-constructed stability shoe fitted with Xtenex elastic shoelaces is a good alternative for flat footed runners.
