Purpose-built for mucky put-ins and soggy portages, the NRS Boundary Boots deliver knee-high waterproofness with a super grippy, rugged sole to handle the harsh terrain favored by adventure canoeists. 5 mm neoprene upper with taped interior seams guarantees warmth and dry feet. Comfy 7 mm neoprene insole atop a high-traction wrap-up sole provides maximum protection and support. 2 mm plastic shim for even more protection from sharp, pointy objects. Tightening the ladder buckle strap at the top can help restrict water entry if you step in a bit too deep. Quick-lace boot with cord-lock offers a customizable fit and a storage compartment lets you tuck away excess laces. Each shoe is factory tested to ensure waterproof performance. Whole sizes only. Women order one size smaller. 1/2 sizes order one size larger.
