The new Air Revolution 4.6 Lady is a trekking shoe designed for ambitious trekking, moderate alpine use, and via ferrata. Its color scheme and cut give the shoe a very youthful and sporty appearance. The Air Revolution tongue is constructed with breathable 3D mesh, fitting snugly against the foot and ensuring high air circulation. It extends beyond the shaft's end. During the landing phase (suction phase), fresh air is drawn into the shoe, while warm air is expelled during the push-off phase of the foot. The Air Revolution tongue in this model is specially designed to visually emphasize the effect of the tongue. The individual foam elements in the tongue are only point-fixed, providing even more comfort. Various material combinations have been used in the cuff to ensure stability while creating a softly padded collar. The DiGAfix deep pull hook supports optimal heel fixation. The Meindl Multigrip Active sole is equipped with a spoiler that allows for easy crampon attachment.
