Just tried on a 10 in the Dark Ops. Was wearing some Nike Elite Versatility socks so I could get a feel of what they'll be like on the court. They felt a little tight in the toe box. I have a bunion on my left foot, and it felt like the shoe was pressing up on it. Also, I couldn't really wiggle my toes or stretch them out. But I figured that'd come with breaking them in. I did have some heel slippage, so I asked to try on a 9.5.
They didn't have the Dark Ops in a 9.5. So I tried on the Below Zero. The heel slippage was gone. Oddly enough, i didn't feel as much pressure on my bunion, but I did have the same issue stretching/wiggling my toes.
I was thinking about having them order a 9.5 Dark Ops. But I'm afraid of the tightness in the toe box not going away. I currently wear the Kobe 11 EM to play ball in, and I'm tired of my pinky toes getting blisters and my bunion hurting.
