If you can get soccerr shoes with support too and you want to pay for them then go for it. Like I say, insoles can be a cheaper option.
You should be trying to wear appropriate footwear as often as you can even in home. The more your foot is in correct alignment the less pain you'll get.
Via Wolff's Law: The internal architecture of the trabeculae will undergoes adaptive changes, followed by secondary changes to the external cortical portion of the bone, as a responce to external stresses on that bone. Hense there is every possibility that with long term use of footware that biomechanically corrects your alignment that your bones will remodel to match that.
You should start a strengthening program also however so your not neglecting the muscles.

good luck
