term for a pleasing, continuous shape of the featherline of the forepart of a last
A last is said to “have range” when the featherline around the forepart is smooth and joins pleasingly with the curves of the ramp.
Range has been defined as the harmonious blending of the spring and pitch. It is understood to define the contours of the edges of a last. The range is good when the curves of the edges are in harmony and continuous. The range is broken when these conditions are not satisfied. This does not apply to the profile but only to the bottom. Suppose a person is looking longitudinally along the bottom of a last with the toe pointing to the observer. Then the edges of the forepart along each side should harmonize. Otherwise it is considered "out of range".
