I'm a 6'1", 240lb male. My feet take a lot of abuse from all the exercise I do daily. I sometimes train barefoot (i have my own gym in my basement) to increase my ankle strength.
Bottom line, the bottom of my feet were BAD! dry, brittle and hard, especially on the heel and big toe. I tries several other products before this one, because they were significantly cheaper. nothing worked.
then I finally bought a tube of this. with a week, there was a big difference. after the first tube, my feet felt and looked great. i now use this daily and am subscribed to amazon's subscribe and save service to have this sent to me every 3 months at an even bigger discount.
from my experience, you need to make sure you use enough of this when you apply. dabbing a bit here and there doesn't work for me. i had to generously apply this when using it. this means that a tube only lasts for about 2-3 weeks with 1 application a day.
tip: try putting this on...
