1, alpha boost is cheap and ultra boost is expensive.
2, ab market is big and easy to buy, cost-effective, and the foot feeling is much worse than UItra.
3.UItra adopts midsole, and ab is a kind of EVA.
The booster materials are different. Ub has a stronger boost. It's better to bounce on ub, and I think ub is better in softness (I don't have an alpha, just try it on, and it feels quite hard. I don't know what will happen if I wear it for a long time. )
Performance ub completely crushes alpha. Running on the road ub is definitely the first choice. I don't recommend running with Alpha here. However, it is better to go to the gym for training and wear Alpha every day. Without a strong package, it wouldn't be so uncomfortable.
Alphaboost is indeed the hardest shoe in boost midsole. After all, it is the beginning of Alpha. This is a consistent feature. I like fitness, but I don't run long distances. Being a soldier for many years has not been spoiled and is not too picky about comfort. As long as the overall style conforms to my personal temperament, I am satisfied.
