Before I bought my first pair of Jordan 4s recently, I did a lot of searches on sizing. The great narrow vs wide debate was front & center, but one thing I didn’t see much talk about, is length. These things are freaking short. I’m a 10.5 & my toe is right to the end. Just like in Air Maxes. If you’re a half size in most Jordan Nikes, go half size up for these. I’m 10.5 perfect fit in all the J1s I’ve had. J4s are just a touch shorter.
