For developing fast 32nds with your feet here are some exercises I have found usefull.
Try loosening your pedal tension and working heel down as you will fell the motion of the notes in your front of your calfs.
Work with a metrenome and start working one foot at a time. try to remain relaxed and just work your ankles.once you feel comfortable simply raise your heel slightly off the ground and try to tap the notes with your toes and use the spring action in your ankle.
remember the more relaxed you are the faster you will play.
Once you reach a comfortable speed and are playing relaxed and clean as fast as you can go try tightening up the pedals as you see fit.
Heel toe is the easiest way to do fast bassdrumming but I always teach my students single stroke techniquews as well using heel up and heel down in ordre to build all the muscle groups
This will help you with control and speed
Another suggestion is topractice playing on the floor and slowly increase your speed .
Then go to your pedals and try it on the drums.
good luck
