My feet hurt when i skateboard?

Whenever i skateboard, after i do ollies, or try shove its when i land my feet hurt pretty bad and i have to stop it feels like my feet have been shocked, can only bear it for about an hour before i have to go sit down and break. My shoes were loose so i tightened them up thinking that would help.. it kinda did but then they started hurting again, is it because im not landing my feet correctly? Should i try and be looser and not as tense, im tensed up cuz i think im gonna fall
