what are the best stretches & exercises to do before skating?

So I'm a new skater, and I'm starting to get into moves now that invole edge control. I've made it to where i needed to loosen my trucks a great deal to be able to get the edge that i need, for moves like the dip, or a jb sway. The problem i am having is when its time to come back off that edge I feel like I have no assistance from the skate at all. Is this normal, and something that will take time to get used to, Do i need new cushions, and if so any recommendations? Im currently running the riedell powerdyne thrust plate with the orange color cushions.

Donald O'Connor from "I Love Melvin" - 1953. Fred & Ginger did great skate/dance routines and so did Gene Kelley. One youtube I love to watch is: Old Movie Stars Dance to Uptown Funk (https://www.youtube.com/watch?v=M1F0lBnsnkE) No roller skating but damn.

Hi, I am just getting into rollerskating. I am confused on what type of skates to get for myself. The skating rink I go to only goes up to a size 13 and sadly I wear a size 15. I was recommended to buy some SureGrip GT50 skates. Are there any other (if better) skates I should get before confirming the purchase?
