Men's off-white Duck & Fish Waterproof Neoprene Boots. Adjustable Velcro ankle strap and outside zipper closure. There is a variety of neoprene boot options out now. Duck & Fish was there long before people started realizing how versatile this boot can be. The soles and heel on this pair act like a protective shell. You can walk over any obstacles on the ground. If you're looking for surfing booties, this isn't what you're looking for. These are more for hunting and fishing on any terrain. Neoprene is not waterproof. It absorbs and retains water and warms by your body temp. I bought these new and only tried them on and walked around indoors with them. Out of my personal collection. Men's size 11.
