Kokatat Portage Neoprene Kayaking Shoes - Portage Neoprene Kayak Shoes by Kokatat are new for 2012. The Portage is the ultimate creeking bootie, with a durable traction outsole and fiberboard insert for comfort while scrambling on shore. The exclusive covered lacing system allows for precise volume adjustment and fit, while ensuring no snag hazards inside the boat.
Weeds, rocks, branches, and stumps line the route to and from your choice creeks, rivers, lakes, and beaches, so Kokatat gave the new Portage Neoprene Shoe a sturdy insert and grippy outsole. And since you're main goal is to keep your feet warm when you're in the cockpit, Kokatat crafted the Portage shoe with three-millimeter double-lined neoprene.
Ideal for whitewater creeking and sea kayaking, the Kokatat Portage is a great 3 mm neoprene paddling booty with a durable traction outsole and flexible midsole. This product will be shipped directly from Kokatat and will leave their warehouse in 1-2 business days. Eligible for UPS ground shipping only.
