After discovering that most people wore lace up shoes rather than buckles in Scotland in the mid 18th century I ordered another pair of Fugawee 1758 shoes ( this time half a size smaller ) , cut the latchets off and punched a couple of holes per side for leather laces. The laces shown in the photo below slip when walking so I'm now using black cotton tape instead. But will try to find some strong leather buckskin in black if I can . One good point is they are more comfortable than buckles and more common to the period . It seems that buckles were only worn by the upper class in Scotland and as I'm trying to portray someone of middle class the lace up shoes are the better choice.
