Picked up the Pioneer colorway when the Xhibition deal was posted. Got my first run in them today... and have nothing but good things to say about em.
I stayed TTS, and there was a little bit more volume in the toe box than what I'm used to compared to my true size 12 in Nikes. Weird but it wasn't really the length that bothered me but rather the height of the toe box. After double socking, which I normally do any way I was good to go. I found them to be very similar to the CLB 2016, which are one of my go to hoop shoes (after adding an extra eyelet to eliminate the heel slip)...biggest difference being that the Continental rubber sole on the CLB is money while the traction on the Harden was just good, not great. BTW, didn't notice the weight of the shoe while playing in them unlike the D Rose 7 for example.
Looking forward to another run in these later on this week!
