It would be obvious to compare this sneaker to its UltraBOOST and AlphaBOUNCE competition — both feature their respective brand’s knit technology on the upper and vamp as well as a protruding midsole/outsole system — but I believe it’s actually more comparable to the FUTURECRAFT 4D in terms of how light and breathable it feels. Entering the sockliner of the sneaker, my foot immediately felt secure and fastened, something that the UltraBOOST lacks and AlphaBOUNCE has too much of. While comfortable, I always feel uneasy that I’ll turn an ankle in a pair of UltraBOOSTs because of a lack of support in the heel area. On the AlphaBOUNCE, I always feel too constrained and immense pressure on my foot from its rigid form. A perfect balance of stiffness is surprisingly present in the FUTURECRAFT 4D which utilizes Digital Light Synthesis, a completely different construction than React foam but with the same results.
