Abstract
A sole of a baseball spiked shoe has a toe portion projection, a first metatarsal head projection, a stepping portion projection, and a fifth metatarsal head projection provided at a fore foot portion at the bottom plane of the shoe sole, and a heel medial projection, a heel anterior projection, a heel posterior projection, and a heel lateral projection provided at the heel portion. Each projection is provided at an appropriate angle with respect to the longitudinal line of the foot.
Claims14
A method of measuring shear stress distribution on the sole of a spiked shoe comprising the steps:
- moving on a plate sensor according to predetermined activities while wearing the spike shoe;
- measuring a compressive stress distribution on the shoe sole at a first prescribed sampling interval using a sensor to generate a signal indicative of the value of the compressive stress distribution;
- measuring a three-dimensional stress distribution on the shoe sole at a second prescribed sampling interval using the sensor to generate a signal indicative of the three-dimensional stress distribution;
- and
- generating foot stress distribution data and load vector data for the shoe sole based on the signals generated by the sensor;
- whereby the shear stress distribution on the shoe sole is measurable from the foot stress distribution data and the load vector data.
An arrangement for measuring shear stress distribution on the sole of a spiked shoe comprising:
- a sensor device for measuring stress on the sole of the spiked shoe while wearing the spiked shoe during predetermined activities;
- and
- a processing system, including a central processing unit, operatively coupled to said sensor device for analyzing the three dimensional stress distribution measured by said sensor device and generating foot stress distribution data and load vector data.
