I'm flat-footed!....(snif, snif)....all my family is that way, long toes also, ugly feet!....I used to stumble over my own feet a lot, especially when I played basketball. Low back pain? Never had it, only pulled the lumbar muscle a few times......(honeymoon night on a waterbed)....and lifting free weights.
Funny thing is....back in the 60's I wore a size 8-1/2-9 shoe....now I wear a 7 and one-half!....It's not my feet, it's my long toes!...And to top my rant off....the heels of my feet are super sensitive!...They blister very easily, so I wear open heeled shoes. Whenever I do have to wear high-heels, people have said I sounded like a "horse" when I walked, and drug my feet a lot....So...I practiced picking my feet up as if I were tip-toeing "thru the tulips"....A model?? I'm not!
