It looks like he glues an additional layer of leather and welt on it. Don't think he replaces the insole for the top one. For the bottom one it looks interesting; there's a lot of gap between upper nailed at the heel and the insole, and the cavity creates by the welt and the insole is quite pronounced with his technique of no carved holdfast. Maybe DWFII could shine some light on the issues.
