The Corsair from Northwave focuses on ease of use and precision. The side locking button can be pressed to gradually loosen the closure. Or it can be lifted and opens fully immediately. The twist lock is additionally secured by a velcro fastener. The Corsair is otherwise made of light mesh fabric with soft straps to reduce pressure on the foot, a non-slip natural rubber sole and polyurethane-reinforced areas on the heel and toe.
