This is the raw data for the article "Algorithm for Gait Parameters Estimation Based on Heel-Mounted Inertial Sensors", which includes walking data recorded by IMUs and data recorded by an optical motion capture (OMC) system, where the experimental data consisted of two parts:

Validity Experiment Data includes gait data (both IMU and OMC) of 30 participants who were instructed to walk in a straight line within the motion capture area and return upon reaching the end to ensure a sufficient step count.
