shown along track 24 until buttressing the tip of the further extending toe as the left toe slider 6 slides along guide 16 to the correct left toe measuring position in this manner the operator need not eye ball the toe length measuring position this optional configuration has the advantage that all of the sliders 4 7 slid to the correct measuring position when a respective slider surface buttressed against the human foot at the correct location without the need for human eye ball measurements and interpretations referring to fig1 and 2 the embedded microprocessor technology preferably comprises an oscillator 28 providing the sensing signal to the rails 17 and 21 the sensing signal is coupled from rails 17 and 21 over ground lines 19 and 22 to fingers 19 and 23 and into multiplexers 29 and 30 respectively the number of width multiplexers 29 and 30 and fingers 19 and 23 may vary but the length of row of fingers 19 and 23 corresponds to possible lengths and widths of a human foot for example but in the exemplar form there are twelve length multiplexer 29 only one of which is designated as such for clarity and there is only one width multiplexer 30 as shown the position of each sliders 4.
