No, they are not the same. UltraBoost, a shoe from Adidas, is a high-performance running shoe with boost technology, while NMD is a lifestyle shoe for everyday wear. It makes them incompatible with each other, and you will have to purchase both if you use both. However, the NMD Runner will be released in the middle of next year. By then, the UltraBoost will be released, so they are likely to be considered the same.
