Honestly, I cannot differentiate between Ultra Boost and Energy Boost, and all the other Boost models out there. As far as I can tell, sole is the same with a slightly different upper? Anyway, I don't like my EB - they fit smaller and are not very comfortable for running.
The Adidas Boost series have a very interesting silhouette - even without 'Ye I would have bought a pair or two. If you study the design, you'll notice there isn't much to tweak in terms of colour blocking, so in this day of hipster triple black this and triple white that, the Boost and Tubular series sell easily because there are only so many colour palettes.
Of all the Nike silhouettes, my favourite are perhaps the AM87, AM90, and AF1. They have that very classic shape, can have some great colourways, and the occasional use of interesting material. The only gripe I had with Maxes was that the ribbed, nippled design on the sole didn't go very well with driving.
Here are some of my faves:







My small addiction started first with the AF1, then I moved onto Nike SB, Air Max, a few Air Jordans and then back to Air Force 1, where it abruptly ended. I've stopped buying, but I still keep an eye out for good colourways. My older shoes, ones that were stored properly, have stood the test of time, but almost every other pair which I forgot to seal (1999-201x era) have all crumbled. Even my 2002 AF1 Glaciers have crumbly soles.
But, like
metaled, I too now prefer comfy footwear. I'm usually in a pair of slippers
