This might demonstrate better. You can more clearly see the stitching here, and its relationship to the edge of the welt / sole. I used to wear them once a week at least. The sole is getting pretty thin at the ball of my foot, and I sense that it is getting a little "spongey". I don't wear them often anymore, so I have neglected to look into my resoling options. Also, I've fallen out of favour with Vass due to the inconsistencies in sizing, and my new preference for less aggressive lasts.
