Crampons pour fixation provisoire sous des chaussures, par ex. des bottines, présentant une partie antérieure et une partie postérieure reliées par une paire de courroies. La partie antérieure correspond à la partie antérieure de la semelle de la chaussure et comporte un embout. La partie postérieure correspond à la partie postérieure de la semelle de la chaussure et comporte aussi un embout. L'embout antérieur est conçu pour loger le bout du pied de la chaussure, et l'embout postérieur pour loger le talon de la chaussure. Les courroies relient l'embout de bout du pied à l'embout talonnier en passant de chaque côté de la chaussure. Elles sont situées au-dessus de la partie antérieure et de la partie postérieure des crampons, de sorte qu'elles ne touchent pas le sol lorsque les crampons sont fixés aux chaussures. Les courroies passent sur le dessus de la chaussure et s'attachent ensemble par un ruban VELCRO? ou autre matériau à boucles et crochets assimilé pour empêcher la partie postérieure du crampon de se détacher de la chaussure. La face inférieure des crampons présente des sculptures et des pointes pour empêcher de glisser.
