    摘要: A novel method of temporarily locating an insole on a last bottom. The insole comprises discrete forepart and heel portions joined by an extensible portion, the forepart and heel portions each having locating holes therein to facilitate positioning of the insole on the last. Preferably, the forepart and heel portions are joined by means of extensible material such as polyurethane foam interposed between overlapped margins of the two portions.
