Felt soles can offer stable footing in most types of stream substrates but may be poor choices when working in areas of extensive clay stream bottoms or snowy banks. Felt soles will provide poor traction on clay and snow will stick to and accumulate on felt-soled wading shoes. Wading shoes with cleats (aluminum or tungsten) will provide stable footing in a variety of substrates (gravels, cobbles, clay, large boulders) and are less likely to transfer invasive species from waterbody to waterbody.
