13264140, Ultra Boost 3.0 seems unusable for running to me

Because the upper stretches so easily.
But I believe I’ve heard that the first 2 versions used a sturdier and less stretchy knit for the upper, at least in comparison to the 3.0. Not sure about the 4.0’s. But I definitely won’t even bother doing much running in the 3.0’s.
