A retractable spike system for providing traction when desired under the entire surface of a footwear sole and heel. Two or more retractable spike assemblies are inserted into cavities in the sole and heel of the footwear. The spikes on each assembly can be engaged by a cam or wedge pressing on a carrier plate. All the assemblies are connected together by a rigid coil attached to the cams or a shaft to which the wedges are fixed, in such a manner that a single mechanism can simultaneously retract or extend all the spikes on all assemblies.

Système de pointes escamotables pour fournir de la traction lorsque désiré sous la surface complète d'une semelle et d'un talon de chaussure. Deux ensembles de pointes ou davantage sont insérés dans des cavités dans la semelle et le talon de la chaussure. Les pointes dans chaque ensemble peuvent être enclenchées au moyen d'une came ou d'un coin qui appuie sur une plaque porteuse. Tous les ensembles sont reliés au moyen d'une bobine fixée aux cames ou d'une tige à laquelle sont fixés les coins, de façon à ce qu'un seul mécanisme puisse faire rentrer ou sortir simultanément toutes les pointes sur tous les ensembles.
