Adidas shares rose Monday after getting a a high-profile boost from its new Adidas Adizero Adios Pro Evo 3 shoe.

Sunday’s three London Marathon winners, Kenya’s Sebastian Sawe in men’s and Ethiopia’s Tigist Assefa in women’s, as well as second place men’s finisher Yomif Kejelcha, each wore the new Adidas shoe. Sawe set a new record of 1:59:30, while Assefa also set a new record for women at 2:15:41. Kejelcha finished at 1:59:41.

Shares of the German sportwear maker rose on Monday nearly 2 percent in early afternoon trading on the Frankfurt Stock Exchange to 138 euros ($162) a share, before settling in the range of up 1.4 percent to 117.74 euros ($138.20).

So, what’s special about the new Pro Evo 3 shoe?

This new super shoe, which debuted for the first time in London, is the first to weigh under 100 grams — 97 grams for a men’s size 9.5 — and improves running economy by 1.6 percent, versus the Pro Evo 2. Most of the reduction is from a new Lightstrike Pro Evo foam compound that is 50 percent lighter than prior blends. But the 30 percent weight reduction comes at a price. The new shoe costs $500 a pair and became available for purchase on Monday exclusively on the Adidas app to be followed by a wider release this fall.

Since its launch in August, the Asics Metaspeed Ray held the title of lightest running shoe on the market at 129 grams for a men’s size 9. Nike’s bestselling Alphafly 3 — the Alphafly series is considered the standard for super shoes — weights more than twice as much as the Pro Evo 3 at 218 grams for a men’s size 10. While Li Ning has gone even light with the Dragonflight at 103 grams for a men’s size 11, the 2023 concept shoe hasn’t yet gone into production.
