OTB ODHIN Boots were designed and engineered at the request of the U.S. Navy SEALS. A maritime boot for use in any rocky or muddy situation, the sole unit also works well in dry conditions. With its superior fit and drainage features this boot also works great with a pair of waders. These boots have emerged as a big hit with wade-in anglers, cross-country hikers, hunters and others who get their feet wet. Main innovation? Tiny holes on the bottom let the water drain fast but stop pebbles, shells and even sand from entering. (www.otbboots.com)
