Yes, the Canvas and Leather shoes have been reproduced for re-enactors and were popular prior to the War in Civilian wear. So they were not a product of necessity brought on by the shortage of leather during the war.

But that is what I am getting at. The shortage of shoes in the Confederate army seems to be because of a number of factors not necessarily the shortage of Leather. It seems to be more a combination of hard usage during the Campaigning Season combined with the poor Quartermaster supply system. These seem to be the two primary cause of these shortages of shoe and the necessity of the "Longstreet Moccasin". Now this does not mean that leather was not in short supply. For example, you do not see confederate soldiers with leather slings on their muskets in early war photos. You do see canvas sling imported from England, along with Canvas cartridge boxes and belts, but for important items like saddles and harness you don't hear of substitutes being used.

In some ways I'm not covienced that the lack of leather and the need for substitutes such as alligator hide isn't something of an "Urban Legend" myth that has sprung up over time. I know that there are plenty of reports and family oral histories of the lack of shoes in the Confederate Army including my GGrandfather. But, I am not completely convience of the natural and cause of those shortages given the whole overall supply system problems of the Confederate Quartermaster Dept.
