"Built to run, jump, swim and climb in and around the water." "Super sticky G.ss Rubber™ + Flex Grip™ outsoles adhere to wet and dry rock like glue. Non-marking and non-rigid." "Conforms to the ground, because this ensures the greatest surface area is in contact with the ground, maximizing friction. Astral’s midsoles and outsoles are finely tuned to be softer and more flexible, so that you can ‘feel the ground’, which is critical for gripping irregular terrain." "By combining a Level Footbed® with a wide toe box, Balanced Geometry™ respects the foot’s natural position." "We are most balanced with our feet flat on the ground. Our Level Footbed® allows the foot to stand, walk and run in a flatter, more balanced position. This design approach, also referred to as ‘zero drop’ allows the body to function in the way it was naturally designed." 100% post-consumer recycled polyester canvas and webbing uppers.
