Here's my 2c:
you got the pain because you were challenging yourself, doing something that is hard for you, and you were very stiff. This happens to new riders when they are all tense.
When you cooked them, did you ask for the fat toe cap? You can heat mold more than once, btw. But if they are comfy around the house and with bent knees toes are OK, I think the fit should be good.
ps: where do you ride? We just closed Alpy yesterday
