If you walk a lot or stand a lot, you likely suffer from rough feet syndrome (especially if you leave in a city). Slather on a great cream after a hard day's walk & cover feet in socks.
Some great products include:
Barielle Rejuvenating Foot Treatment is heavy duty. According to the company's website, it exfoliates skin & softens calluses with a 'time-released' dose of alpha-hydroxy acids. Alrighty then! All we know is we have tried a ton of foot balms -- from the Body Shop to our local drugstores -- and this one is the best of the bunch.
