The Nike Air Max 2021 SE Grey Black Dark Teal introduces an innovative cushioning system under foot and offers a utilitarian aesthetic on the upper to create a dynamic shoe. The upper of the Grey Black Dark Teal Nike Air Max 2021 SE is built upon a base of gray mesh with darker woven textiles at the eye stays and heel counter. Black synthetic material forms both the padded collar and the side panel Nike swoosh. Pull tabs to ease on/off hit the heel, tongue, and eye stays. Exaggerated zig-zag stitching peppers the upper in white and pale blue, and pale blue stitching forms an XXV on the heel counter to commemorate the 35th year of Air Max technology. The black rubber outsole is lugged for grip. The most dynamic and noticeable aspect of this sneaker is its midsole. The black foam is hollowed out into two connected compartments under the heel in order to form a collapsible area that houses a dual Max Air unit with jade tinting. The Nike Air Max 2021 SE Grey Black Dark Teal was released on April 8, 2022, for $160 retail.
