All my women (Hi-fashion Vickie, Supermodel Vickie, Ingenue Vickie, Glamorous Vickie, Posette 2003, etc.) have the ever-popular Hi-heel feet and know how to walk in heels, even in Walk Designer, as you noted. I've also hand modified animations to make regular Vickie walk corectly in heels, but it is a lot of work- try deleting, in all but about every 3rd frame, the bend settings for the feet and toes, then go back and adjust what is left. I'd like to see more done with Poser and animation, I was playing around with a walk cycle the other day, trying to get the nice feet-crossed-over walk that the girls from Brazil do on the catwalk, Gee, what a lot of work!
