I buy them several reasons;
1) I feel more comfortable with dainite soles rather than leather soles during the winter.
2) It doesn't wear nearly as fast or is as slippery when it rains compared to leather soles; which it does a lot here.
3) There are no cobblers near which can change soles, and shipping to U.S. is mighty expensive.
4) I often like the more rugged look of dainite on boots or heavier brogued shoes.
Well said. I've never understood all the chatter about Dainite being poor in winter. Snow and ice must be different where I live. Way better than leather, in my experience - and differences between it and other synthetics amount to splitting hairs.
Oddly enough, I was just reading a novel last night where the protagonist was extoling the virtues of Dainite soles on his Cheaney shoes. No, I'm not making that up.
