HTM = collab between Tinker Hatfield (designer of most Jordans), Hiroshi Fujiwara (Fragment design founder which also has limited collab with Cole Haans LunarGrands) and Nikes CEO Mark something (forgot his last name). HTM is pretty much the initials of those 3 peoples first names.
Pretty much pairs with the LunarSoles are HTM. The Lunar One+ that is coming out with a LunarSole has a different sole, it has the LunarGlide4s sole. The initials HTM is also printed on the tongue but other than that, they are also distinct in colorways.
There is also some USA edition that are also very limited, I think it was only sold in London, I could be wrong though.
I just wanted this pair though, god Nike is so stingy.
