Is a "flex welt" aka "oiled flex leather" sole the same as a "waterloc" sole?
Is a "double waterloc" sole different from a waterloc sole?
I'm confused, because I've seen Leffot refer to a flex welt sole as a "double water-lock" sole (link
), whereas Winn Perry has claimed a "double waterloc" sole is "a stacked version of the soles used in the construction of Alden's flex welt system" (link
If there are single- and double-sole versions of the oiled flex leather sole, is the single-sole version still OK in the rain?
