Xtratuf Women’s Sharkbyte Sustainable Shoes are a new take on Xtratuf’s Sharkbyte shoe. They are now made with ECONYL upper which is 100% regenerated nylon fiber made from fishnets and other nylon waste. They’re slip on style shoes that are versatile for a long day out on the boat deck or just heading out to dinner. Functional without giving up style. These shoes were made for your next fishing trip with water resistant upper with maximum water repellency. The slip-resistant outsoles will hold up well on deck with its super grippy rubber compound.
