Vintage shoe laces is one of the best item for your boots, no matter you are wearing Red Wing shoes or other brand, it comes with another feel and it represent your taste. Vintage shoe laces did not mean used or 2nd hand, sometimes it is just dead stock or keep in the warehouse for some time.
It is not easy to find one, you can just get one by luck, so if you have time, go and take some time to explore the 2nd hand shop, vintage store, especially when you go to Thailand, Taiwan and Japan. They got a lot of vintage good stuffs.
