Water retention: I cannot tell what may be causing soreness on pressure, however, if it is getting worse after salty snacks, that is likely due to water retention due to excessive salt intake. The background soreness may be due to low level inflammation in the soft tissues of the foot that may need to be investigated by a doctor.

Fluid retention: Due to the salt you are probably retaining fluid.
