Designed for both waders and stand-alone use, these booties are crafted from high-quality neoprene material known for its flexibility, durability, and insulating properties. The stretchy nature of neoprene hugs the foot snugly, preventing any unwanted entry of water or debris. This makes them an essential component of a fly fisherman's arsenal, especially when navigating through uneven riverbeds or braving chilly mountain streams.
