Seeland Noble Gusset is a carefully designed rubber boot. It has a 5mm neoprene lining, an adjustable buckle, and is made from strong 1.8mm natural rubber, reinforced around the foot and especially at the heel and toes. This makes the boot both flexible and durable. The outsole is made from two different-density rubbers for extra comfort and to ensure a very strong join between the sole and the boot. The sole has a central tread pattern designed to prevent the boot sticking in the mud.
