Shoes made with spray, dusted, nitrogen infusions, and hollow plates: the gram war revolutionizes the marathon again

The race for lighter marathon shoes intensifies as brands innovate to reduce weight while maintaining performance. Technologies like On's LightSpray and Adidas's new foams aim to create shoes under 100 grams. Mizuno's Hyperwarp 96 exemplifies this trend, focusing on minimalism and exclusivity. However, achieving extreme lightness poses challenges in comfort and stability, raising questions about the limits of weight reduction without sacrificing essential features. Experts believe the future lies in finding the right balance between weight and performance, as the quest for the ultimate marathon shoe continues.
