That old one held up pretty nicely despite being used everyday for 3 years! Some of my shoes before give up easily, especially those rubber part on the soles they just separate lol.
It's quite hard for me to buy shoes online because I found the sizes to be very inconsistent despite the "universal sizes"... so I don't do it as much. But when I do, I have to get a ruler and measure my feet manually and choose the sizes according to the in/cm they have, and not the standard "sizes".
Maybe you'll see the exact same shoes on sale next time or a new one in the same series or something. I do agree it is better to shop in physical stores but that will cost so much more.
Perhaps in the next few days I'll be able to visit an outlet 30 kilometers from my home. I've been told that they often have some Adidas UltraBoost models available! I'm crossing my fingers.
