Такая подошва вроде бы изначально была придумана для сталеваров, асфальтоукладчиков, строителей. Волнистый протектор давал повышенное сцепление с асфальтом, металлом или элементами конструкции, а толстая подошва предохраняла ногу от прокола, если наступить на гвоздь/штырь и т.п. Плюс неплохая амортизация позволяла ходить на такой подошве целый день

3) Christy soles, as very often seen on Red Wing, Grenson and others. These are the thick, heel-less foamy-looking white soles used on both work-boots and brogues alike now. They do provide a new look on old designs, which is nice, but do they really improve matters? Red Wing claim them to provide lots of traction in the workplace (not the same workplace as mentioned above, but an actual physically inclined workplace where there is real dirt, danger and un-curated facial hair).
In my experience though these soles have a couple of grievous issues:
They have no grip at all. I see mention of people wanting to use their Red Wings for winter use and can only comment that they are useless on snow and ice.
They have very poor wear characteristics, i.e. the soles wear out very quickly if used regularly (they’ll last forever if you never use them though). When mine wear out enough to justify a resole, they’ll have Vibram commando-soles fitted, which is a nice advantage of Goodyear welted footwear.
