Foot drop, hammer toes, contracted leg muscles, with a diagnosis of PN all sound like hereditary neuropathy to me. Have you discussed the possibility of CMT with your neurologist? Research the condition on this site and others and see what you think,but PN that causes changes to the physiology of the foot is often CMT.

I should add, in answer to your question, my toes look a lot like yours, my calf muscles are tightly contracted as Mrs. D mentioned, my feet are also contracted with high arches and muscles thinning and I do have CMT.
