Okay, many of us own vintage or reproduction-vintage footwear. In searching through the various posts, there is often mention of adding cushion insoles to make the shoes/boots more comfortable. That got me thinking... What insoles were used in vintage footwear a half-century ago to make them more comfortable? Really, if we were living in 1940 before the days of memory foam and gel inserts, what would we have used? Simply a piece of soft leather? Wool felt? The question came to mind the other day when I was cleaning up my reproduction G.I. service boots. Aside from the thin leather insole, there really is not anything to offer extra support or comfort. Obviously, combat troops spent many long hours in their boots and that got me curious as to what they might have added (if anything besides thicker socks) to give more comfort.
