Got it. 7.5 women's = 6 men's = 24 cm = very small.
Width is a killer for small footed women and while some have gotten very good at riding wider boards, almost all really appreciate it when they get on something appropriately narrow.
The waists on the 149 ET and the Goliath 150 are 24.6 cm (and both are going to be ~ 1cm wider again at her stance position). That means that her toes/heels will be ~ a combined inch inside the edges at a normal stance. That makes it impossible to ride a board to its designed potential.
The Violenza 149 will be a great choice if she can live with the graphics.
