Interested to see for sure. The original idea name for the 30 line was 30+1, 30+2 ….not sure if anyone already knows that but just a fun fact I found out recently from a JB brand member.
I’m assuming the 39 outsole will have some story telling like the 9 did along with the brand taking things...
Don’t use powder. Becomes a mess. I’ve shared this before and I will again. Sounds weird I know.
Lift the insole, spray a tiny little spray of WD-40 where the small air sole unit is. Let it sit over night.
Your welcome…works every time.z
