those kimi insoles are bogus,i mean they say itll increase your height by stimulating muscles in your foot,thats just dumb...and i gotta question about that spine stretching/lengthening..if u increased your height by stretching your spine out,wouldnt that mean u cud lose it if u stop stretching it?and that its not permanent?i was just wondering cuz ther is proof that it works,i just dont know about the permanent part
