The All-Terrain Bootie combines the rock-solid Workboot sole with the flexibility and ease of the Zippered Wetshoe. For hiking and portaging, you'll appreciate the traction, protection, and support of lugged hiking boot soles. But you'll also like the simplicity and warmth of the zip-up 5mm neoprene upper and a wide, secure instep strap. 7mm insole cushions your foot for quick side hikes or a grueling portage. You won't find a better shoe for daily river running. (Whole sizes only) 1/2 sizes order one size larger. Women order one size smaller.
