A shoe comprising an accelerometer making it possible to supply acceleration data (AccX, AccY, AccZ) along three distinct axes X, Y, Z, the axis Z being oriented vertically when the shoe is placed flat on a horizontal ground, said shoe also comprising a control system which comprises: - a memory making it possible to record the data supplied by the accelerometer; - a data processing unit, such as a processor, the processing unit being configured to carry out the following steps: - comparing the acceleration measured by the accelerometer along at least one axis, with a threshold value, such as 6 g, and - based on at least the result of the comparison, triggering the determination of the following parameters: - the slope of the curve (C_AccZf), preferably filtered, of the acceleration measured along the axis Z as a function of time, - the duration, called horizontal position duration, during which the acceleration or the acceleration variation along an axis, or several of the axes (X, Y, Z), of the accelerometer remains below a threshold value; - detecting a drop at least based on said slope and said horizontal position duration, said processing module being configured, if a drop is detected, to generate a corresponding drop detection signal; and in that the control system also comprises a radiocommunication module making it possible to transmit said drop detection signal to a remote receiver. said shoe also comprising a control system which comprises: - a memory making it possible to record the data supplied by the accelerometer; - a data processing unit, such as a processor, - a memory making it possible to record the data supplied by the accelerometer; - a data processing unit, such as a processor, the processing unit being configured to carry out the following steps: - comparing the acceleration measured by the accelerometer along at least one axis, with a threshold value, such as 6 g, and - based on at least the result of the comparison, triggering the determination of the following parameters: - the slope of the curve (C_AccZf), preferably filtered, of the acceleration measured along the axis Z as a function of time, - the duration, called horizontal position duration, during which the acceleration or the acceleration variation along an axis, or several of the axes (X, Y, Z), of the accelerometer remains below a threshold value; - detecting a drop at least based on said slope and said horizontal position duration, - comparing the acceleration measured by the accelerometer along at least one axis, with a threshold value, such as 6 g, and - based on at least the result of the comparison, triggering the determination of the following parameters: - the slope of the curve (C_AccZf), preferably filtered, of the acceleration measured along the axis Z as a function of time, - the duration, called horizontal position duration, during which the acceleration or the acceleration variation along an axis, or several of the axes (X, Y, Z), of the accelerometer remains below a threshold value; - the slope of the curve (C_AccZf), preferably filtered, of the acceleration measured along the axis Z as a function of time, - the duration, called horizontal position duration, during which the acceleration or the acceleration variation along an axis, or several of the axes (X, Y, Z), of the accelerometer remains below a threshold value; - detecting a drop at least based on said slope and said horizontal position duration, said processing module being configured, if a drop is detected, to generate a corresponding drop detection signal; and in that the control system also comprises a radiocommunication module making it possible to transmit said drop detection signal to a remote receiver.
