Some are more effective than others. They are mostly based on the scientific research, but you may be surprised by some of the products that are not in the scientific research. You are very welcome to look at the reviews on the products and make a purchase. I recommend buying only what you like. You can always buy them at a lower price later. It is better to avoid expensive stuff that is not worth it. I am also adding some comments about the products. You should check the reviews if you want to know which products are good or bad. These products are not for everyone, but if you are a pretty foot, then I hope you will find them helpful and you will get a lot of compliments.
If you can afford it, try the other foot products, I won't get into them because they are not important for people with pretty feet. You can order them from this site. I really love these products. They are a great way to add texture to your feet and make them look nice and comfortable. These are for those with pretty feet, or if you are a really thin girl, and you have a lot of big toes, and they are really painful.
