>>1371316I know of welted leather boots with vibram soles and cushioning, but those usually have leather lining, pic related. Don't ask me why. Entirely unlined leather boots are exceedingly rare anyway, all I know are william lennon, ww2 reproductions, danner bull runs, some varusteleka stuff (with brogue caps). The latter two of which do not apparently have soles suitable for the outdoors. I guess a good cobbler might exchange soles or include cushioning though.
