The maximum horizontal force ( force-plate) in the running direction coincided with the moment at which the forefoot studs ceased to travel posteriorly and instead moved anteriorly (3D tracking). This was considered the time of peak push-off and showed agreement between force-plate data and 3D tracking results. The ratio of horizontal to vertical force was greatest at the end of contact. This implied the resultant force was acting in a more horizontal direction, potentially increasing the risk of slipping. It should be noted that at this point only the tip of the shoe was in contact.Further investigation into the orientation and velocity of the shoe during different movements with a larger data set is currently being undertaken.This will lead to a comprehensive database of boundary conditions suitable for traction test devices.
