for Jordan 1s I usually buy an insole for em from Dr.Scholls or whatever but since I also recently got a pair of Timbs that fit super tight cuz of the surprisingly thick ass insole, I just switched the two and they both now fit perfect
I was disappointed at first cuz half size down is good on all my old Timbs. I had to ship it back for a full size down which ended up fine lengthwise but only fit good without the insole. Jordan 1s got a flimsy insole and underneath these Timbs felt like a hardwood floor with 2 exposed nails - so this was best case scenario
