Probably bad circulation to the extremities. Two ?'s

1. Do you notice the same thing in your arms?
2. Have you tried the capillary refill on your toes?

Squeeze you big toe nail and if it doesn't go from white to red, then there is bad circulation.

my calves always get really tight, not just in the back but all over, the front too.

i dont know if its how im running or whats wrong, i think i run using too much of my lower legs and not enough upper leg movement, and im too straight in my upper body, i dont know.

humm, I dont think it is, but research shin splints ( do a search on here) could possibly be that?
