When customers try on shoes at the point of purchase it is important to ensure that the buyer's foot length is appropriate for the shoe being considered. The SATRA size stick is a convenient way to achieve this. Shaped like a calliper, this device has dual scales – English shoe sizes and millimetres.
Since the foot spreads when a person is standing this is the best way to measure the foot (with weight on). The scales on the SATRA size stick are adjusted to measure feet in this way. Both left and right feet can be measured using the device and the scales are so angled that either scale can be easily read.
The SATRA size stick is easy to use – simply place the fixed anvil behind the heel and move the sliding calliper up to the longest toe and read the indicated size.
