The soles of my shoes are pegged with wooden nails, two rows, becoming asymetric towards the toe. Cleaning up another fairytale about pegged shoes. Of course, the welt is (hand)stitched to the sole.
Next time when you are in Vienna, you can ask Materna, Balint, Maftei etc. about this topic. These are the real experts.
