A dataset containing IMU recordings with full motion capture reference from 14 participants (approx. 10000 strides). Each participant was equipped with 15 synchronised IMUs (6 at different positions at each shoe, 1 at each ankle, and 1 and the lower back). The main goal of the dataset is to compare the recorded signals of the 6 sensors attached to each foot. For more information about the dataset check the `README.md` file in the dataset.
