I have to say this product is impressive! I had very thick, cracked, and rough as could be. That is the only reason I did not take before/after pics. My heels were so bad they were putting holes in my socks within a day of wearing them. I used this product as directed one time. And my feet as so soft and the next day are still feeling soft. I cant belive the this product works that good. The foot rasp works wonderfully. I will be honest it is sharp but thats why it comes with a cover. Dont be alarmed though because it removes calluses with ease and its easy to see your progress of the depth of the calluses, preventing you from accidently going too deep. In the beginning I thought it was going to take 2 treatments to get through my bad callused heels but I only need to use 1 treatment. I have used alot of different home foot treatments since I was a teenager, I am now 38. This is my %231 go to for calluses from now on as long as the ingredients dont change. I highly recommended trying!!!
