@AnimalFear’s right. 703 and 704 are the same last. 704 was just stiffer and lighter.
@bengels you might like the True Catalyst line when it drops this summer. True is close to the Graf cut, about an eyelet lower than standard boots. Catalyst is supposed to have a bit softer flex to it, which makes me think it could be the best of new technology and a boot pattern that works for people who like classic Grafs (I’m a die hard 703 guy myself).
