I would supplement with vitamins, the B's in particular. Riboflavin deficiency can cause this, and can start while the chick is developing in the egg. You can use a human B complex tablet if you can't find a poultry vitamin with riboflavin. The B's are water soluble and extra will be excreted so you don't need to worry about too much of the B's. If the toes are curled the shoes may help. If the toes are not curled then I'd take the shoes off and give the vitamins a chance to help, may take up to a couple of weeks, the sooner you start the better.

Putting the chick in a chick chair for periods may help it to eat and drink.
