This massager is not for people with sensative feet. It is very firm which i find great as thIS is what i was wanting from a massager. When i first placed my feet in the cup like sections,turned the machine on, by gosh i took them straight out again as i wasnt expecting it to be as firm, but after bareing it a couple of times, you and your feet get used to it. I find if you move your feet around in it you can target any spot you want on the sole or top of your foot. Im a size 10 foot, and have broad feet, and have no problems fitting my feet in and moveing them around. It is very close to the feeling of human hands, but as i said, very firm and deep kneading and which the human hand would get tierd after a few minutes. Overall to sum it all up, this is a must buy for someone looking for a strong firm massage, NOT for the faint hearted. Well worth the £42 paid, a bargin when looking everywhere else for the same product.
