Micro-Pedi,is the very best by far.
This Micro-Pedi power callus remover is fantastic....I have used pumice stones,and even purchased the loofah that they use in my nail salon.  Nothing really did the job for my dry cracked feet...this was the best product by far!  I did buy a separate pack of rollers that were made for tougher areas and they did a great job.  I would highly recommend this product to anyone that needs help maintaining their dry cracked feet.
