These XTRATUF Legacy 2.0 Series 15" Neoprene Insulated Men's Fishing Boots feature an updated design, new safety features, and even more protection. Our signature non-marking Chevron outsole still anchors the boot, but it's been upgraded to achieve an SRC rating--the highest level of slip-resistance that can be awarded. From a comfort standpoint, the new contoured topline on these fishing boots is lower at the back to prevent calf-chafing, and features a polyurethane rim for added smoothness. A new form fitting last is specially designed to provide a proper fit for today's fisherman, and combines with a new PU Comfort insole for longwearing comfort and reduced foot fatigue. Designed for subzero weather, these men's fishing boots include polymeric foam insulation for comfort rating down to -10 °F (-23 °C). The protection package is also beefed up with extra layers of rubber at the shin and forefoot to prevent wear from the constant rubbing of foul weather gear. The heel features a new textured finish for easier on/off, but remains supple enough to avoid snagging on gill nets. The tried-and-true, 100% waterproof triple-dipped neoprene design of these insulated fishing boots is unchanged. They feature hand-layered construction for flex and strength at critical stress points, and remain resistant to cleaning chemicals, contaminants and other corrosive substances common to the fishing industry.
