I'm less than 5 ft, 43kg, and wearing Jackson Freestyles (now on my 2nd pair). I've tried the Classiques on but they're just not of the same quality. Further, having leather soles gives you more flexibility on blade alignment. Plus, the Freestyles are heat moldable -- I don't think the Classiques are.
When I got the Freestyles, I couldn't do any single jumps yet. They're initially stiff, but start with lacing only up to the second hook. Work your way up to the third hook (this can take 1-3 sessions), and finally to the fourth hook (may take more sessions, depending on your skate frequency).
I also have feet that are wide in the ball and narrow in the heel. I'm currently wearing stock boots, but would upgrade to semi-custom when I have the money.
tldr: go with the Freestyles if you can go with it
But don't forget to go to a fitter so he can give you the right size. My first pair was too big, but it wasn't until I was working on back three-turns that I noticed it.
