Slugs are a great enhancement to any pair of Xtratuf boots. They offer additional warmth, comfort and style to an extremely versatile pair of boots. The idea behind SLUGS fleece boot liners is from Rayana White who was born and raised in Ketchikan, Alaska, where they measure rain by the foot rather than by the inch! She currently sells SLUGS on Etsy.com a website for small businesses to sell their crafts. I would imagine that as popular as Slugs are becoming, that you will see them in major retails right next to Xtratuf Boots in no time!
