Durable and anti-skid outsole for better traction.• We tested all the neoprene rubber rain boots on wet grass, wood, and mud, in river beds and the ocean, and on ice and snow. The Fujie outdoor took the lead with its heavily studded outsole, allowing us to feel comfortable no matter the surface. These boots are made from high quality natural rubber that won't crack when it stretches. The advantage is that the sole is softer and comfortable. It is suitable for long time outdoor working.
