Abstract: The invention relates to a safety binding for skiing, including a toe piece that includes a body mounted to slide vertically relative to a front mounting base connected to the ski and defining an upper stop for a boot; a device for adjusting the vertical position of the body, which can be manipulated by the skier in the area of the upper portion of the body; at least one lever pivotally mounted relative to the body about a substantially vertical axis between a retaining position and a release position of a boot; and a spring mounted transversely in the body and biasing the lever toward its boot-retaining position.
Abstract: Footwear, such as a sports boot, including a shell or a shell element made of a rigid plastic base material whose softening point is greater than 170° C. and a method of manufacturing such footwear. At least in one local portion of the shell or shell element, the base material of the shell includes an additive having a melting temperature lower than 100° C., in a proportion of between 3% and 45% in a first embodiment and between 10% and 25% in a second embodiment. A heating machine includes a base provided to receive at least one boot along a longitudinal direction defined by the sole and a hot air blower. The heating machine includes at least two air blowing channels facing one another and located on each side of the longitudinal direction.
