To find your foot length, measure the distance between the two longest points on your tracing. Reduce this number by 5 mm, or 1/5-inch. The result is your foot length and the number you will use to determine your shoe size.
Proper tennis shoe sizing and fit is based on the length and width of your foot. The below measurement guide can be a useful complement in getting the best fit for your feet. For reference below there is a men's & women's shoe measurement sizing chart as well as a men's to women's conversion chart.
We calculated C D and C L from the change in speed and ball height between the two positions. The following equations define the drag, lift, and gravitational forces:
Tennis Shoe Sizing Instructions. Now, for each foot, you need to measure the following: The length of the foot. The width of the foot in the widest area.
The magnitude of the couple is given by C = Fd where F is the value of each force and d is the distance between the two forces. The torque acting on the racquet is equal to C. If each force is say 30 lb and d = 4 inch = 1/3 ft then the torque on the racquet is 10 ft-lbs.
The amount of shear will depend on the shear stiffness of the shoe outsole and midsole materials and may be as much as 2-5 mm. True sliding will be the distance recorded by the LVDT minus the shear distance.
