The product I found was Olay Body Thermal Pedicure Foot Treatment. This stuff was awesome! First off, the scrub came out easily, when I rubbed it on my hands it heated up immediately and I swear it made my feet feel softer and clean when I got out of the shower. I purposely did not use my pumice stick in the shower so I could feel the actual results.
The scrub has Bora-Bora white sand which was much more course than the AVON thermal scrub for your face. It worked well on my feet, didn't melt as sugar scrubs do and washed off the shower floor fairly easily.
The scrub also has shea butter which will leave your feet moisturized, but don't be fooled, it is recommended that you also use your own foot lotion after bathing.
I will definitely buy this product again and look for coupons or sales. It is listed at $9.99 on drugstore.com but I can guarantee you that I didn't pay that much.
Good luck and remember that Kate has some good ideas...or at least her spokesperson does. Clean out your closets and quit wasting money on products you already have...like me!
