Hi Marlene:

Will bet the cracking and yellow toe nails are a fungal infection.  Sometimes 
 the nails will also get thickened, and painful.  The cracking feet, 
especially between the toes, sounds like athletes feet.  

Might try soaking the feet in a good solution of hydrogen peroxide, at least 
once a day, and making sure they are dry between the toes.  Cotton socks only.
