Stretching around size & Half

This amazing early pair by Daniel Wegan need to be stretched around 15mm in length, widh & height in order to fit my feet. Enormous care, attention & patience is required, only attempting to stretch a couple of millimeters in one direction per session. It will take several sessions to achieve desired fit. The difficulty is compounded on this pair by the rare 'Double Sole' construction, a practice more usual amongst high end US makers' in the 1930s.
