Soom Mecha Angels are like that, all legs. Some of my 70cm boys sit taller than my Sabik (or Nayuta Kenzo, which I also have). Dollmore's shorter Model boy is also all leg. However, my Nayuta Kenzo never looks short standing up. He's taller than my 70cm boys and stands at least as tall as my 72.5cm Dream Realm boy. I usually have him sitting because he's such a sexy lounging guy, but I found one standing photo -- and even in this group arrangement (I pose my dolls at home in groups) I have him hitching over, as if to talk to the dolls on the bench, just because he can do that pose:
Seated, left to right: Glorydoll Lucy (58cm), Dream Realm SuiTian (72cm), Soom Aphan (43cm), Soom Nephelin (68cm), Soom Teschen (girl body, 43cm). Standing, left to right: Soom Spinel on an SSDF body, 70cm; Dollmore Model Ipsae Moynihan (68cm); Dollmore Glamor Model Nayuta Kenzo (75cm), Soom Mecha elf Sabik (80cm), Dollmore Model Bella Auden (68cm, but has platform heels). The heights are all according to the manufacturer and not heights I've measured. None of the boys are wearing platform shoes. Spinel is the only one whose height is enhanced by a stand platform. He's not really that tall.
