A spur-shrouding device with a spur cover forming a spur-receiving cavity and a retaining strap preferably integrally-formed therewith, and characterized by a penetration-resistant member secured adjacent to the cavity to prevent the spur from rupturing the spur cover. The spur cover and penetration-resistant member are preferably of first and second elastomeric materials, respectively, the second having a greater hardness than the first. The penetration-resistant member, which is preferably configured to secure its position, to fully protect the spur cover and to facilitate spur-cover molding, is preferably pre-formed and the spur cover is molded around the penetration-resistant member such that it forms the closed end of the cavity.
