I have a pair of Patagonia Rock Grip wading boots, and they have superior traction on slick surfaces. They happen to be on sale now at Patagonia's website.
The Rock Grips have the best traction of any wading boot I've used, but I'm not crazy about the fit of the boot. It's okay, but it feels a bit too tight in the toe box area. Also, It's not the most comfortable boot to walk in. If you are looking for traction above all else, it might be the perfect boot for you. If you prefer a boot that feels like a quality hiker, then maybe you'll want to look elsewhere.
Here is a link to the Patagonia Rock Grip sale. They also have another style wading boot on sale for less money, but I know nothing about that one:
