I think I've had the heel problem before(not sure if its the same thing it was like catching the top of my heel bone and it hurt a lot). I used duct tape and like some foam material . just duct tape it down, Seems like you're limited on room for your toes though, too. The only thing I have for squished toes is just bending the shit out of it, like fold sole around a bunch, which doesn't really help a lot or even at all, haha. Toe thing sucks, but best I know is just to wear them, I've had shoes just bruise the shit out of my toes and make them bleed, but after a while it gets better. Also I guess you can wear thinner socks(but this might make the heel thing worse).
