Abstract
An insole is capable of withstanding penetration of nails and other foreign objects. The insole is constructed of a substantially flexible, substantially puncture resistant material, such as a polymer fiber. The perimeter of the insole is curved upward, and includes a plurality of substantially v-shaped notches therein to enhance flexibility of the insole. A downwardly curved portion is embedded in a sole of an article of footwear. The downwardly curved portion substantially mirrors the portion of the perimeter of the insole which is curved upward.
