摘要：
A spike (10) for attachment to baseball shoes has a spike body (11), a leg (14) protruding upright from the spike body and having a distal edge (14a) and an abrasion-resistant tip (20) made of a metal and having a base portion welded to the distal edge of the leg. The base portion (21) has a wedge-shaped ridge (22) pressed to an end face of the distal edge such that the base portion (21) is gripped by and between masses of a once molten and then resolidified material of the distal edge of the leg, so that the spike is abrasion resistant and durable. The distal edge (14a) may have at its middle region a cutout (16) to divide the end face into two parts to which the base portion (21) of the tip are adjoined concurrently and in the same manner.
