NC, mine are about 28 inches, and I use powder. Although, I have to add, that with muscle growth, I've noticed that it goes front to back not side to side. My legs only rub together when I'm fat. In other words, I use alot of powder.
i have 22 inch legs and the insides of mine sometime rub together.. i have large inner thighs....dunno from what, but i do. i dont use anything thuogh.
I have pretty big legs, but dont have this problem. I cant wait til i have it though, becuase it means your legs gotta b huge. This is one problem i will welcome.
The deoderant works good but sometimes can dry you out and make the friction cause your pants to catch on fire(well...def. make your inner thighs hurt quite a bit).
