 These shoes, which had the high-grip herringbone tread, were highly prized by rafters and bushwalkers, who appreciated the dissipation of the friction point at the heel, the reduced entry of sand and debris, and the protection to the ankles against knocks from rocks when wading in rapids.The cotton canvas around the ankle was a seamless extension of the Volley's uppers; it did not seek to 'support' the ankle, only protect it.However, the boot was unavailable by 1983.
