I have my kickflips down just like I could walk. I haven't skated in a week cause my back had some problems. Then today was just like any other. I roll in pop a couple of ollie's and 50-50's but then I tried my kickflip. Nonexistent. I can't flick it right anymore. My foot never flicks fully and ends at the concave. The problem is that when I slide my foot up I can't get myself to do the flick anymore. Its ridiculous. I don't know what's up.
