Abstract For determining a path of movement of a tool along shoe bottom marginal portions a series of points along such path is selected and information regarding such points stored in the form of digitized co-ordinate axis values by computer,from which information the path can subsequently be derived. The selected points are spaced by a predetermined distance (which may be the same for each pair of adjacent points) regardless of shoe bottom contour. To this end, when each point is digitized, the tool and shoe bottom are relatively moved apart by the predetermined distance along one e.g. a heightwise dimension (preferably an axis). Thereafter in returning the tool and shoe bottom into engagement along said one dimension and/or along a second, e.g. widthwise, dimension, movement also takes place automatically along a third, e.g. lengthwise, dimension thus to maintain the predetermined distance. Computer also has interpolation, grading (for size) and reversing (left/right) programmes.
