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 (Z), 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 (Z), 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 (Z), 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 (Z), 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. <EOS>
