The Nike SB Dunk Low, though today an uncontested favorite, once fell victim to lackluster popularity a few years back. After many notable collaborations, the 2002-born silhouette slowly faded into obscurity following the early 2010s’ attempts at turning it into something almost too playful. History is important though, especially for a shoe like the Nike SB Dunk Reps. Do a bit of research. It will make your favorite pair that much more important to you. However, there are still 1s that are best left off your feet like these, for example. Leave these on the shelf, too. 
Yes, creasing is an inevitable part of wearing shoes. No matter how much you try to avoid it by walking around like a duck, eventually the toebox is going to show some signs of age. The good news is, Air Jordan 1s are one of the sneakers that don’t immediately look disgusting when they get a little creased up. However, we still don’t want the toebox looking like a balled up shirt you just pulled out from the bottom of your closet. 
One of the easiest ways to do this, believe it or not, is to make sure you are buying the proper size. Trying them on is the best way to find out, but generally speaking, 1s run a bit narrow. If your foot is wider, go up half a size. If there are two inches of space between your toes and the front of the shoe, size down.
