NikkenKenko mSteps - Insoles 20214 - Men’s Shoe Sizes 7-12, Pair, Cut-to-Fit Design with Magnetic Technology

Nikken Kenko magnets really seem to be bio-engineered with their three alternating rings of charge. The sharpness of the massage points in between the magnets make be a little intense at first... but you can flip the insole over to the other side (switching left and right shoe) and derive the same benefit.I don't want to cut my insoles down in side to fit better; the little bulges of the slightly over-sized insole fit up into the arch and under the base of the toes - giving all-day contact and massage in places you wouldn't feel all-day long while sitting.Most foam-soled shoes have little arch support - and i have size 9 1/2 wide feet. But the softer tops of modern shoes lest the size 12 insole fit inside any shoe.My feet no longer tend to swell, hurt or get hot. The effect is noticeable withing days.Grounding might be a bigger problem than we think - for both bodyworkers and people sitting in from of a computer for hours and hours.Although pricey ... there is no other magnet like the Nikken.And they are cheaper than a visit to the doctor.

Can not say enough good about ANY NIKKEN product. Stand on my feet ALL day and these make all the difference in the world. Feet were NOT sore and tender at the end of the day. Have another pair that do not have the bumps on the foot beds. LOVE them both. Have many Nikken products & have tried many other brands, BUT Nikken is the ONLY one that I buy anymore.

I have tried several different types of insoles and none of them have helped until I found these Nikken Insoles. They are the best ones I have ever had. They are definitely worth the price, I would definitely recommend them to anyone. My feet feel so much better after a long day at work.

It truly doesn't work

Gauss strength & penetration not very good, especially for the price! Didn't do hardly anything to relieve the pain in feet, or calves.

very useful

Although I did wear this a lot over a period of a few years, eventually the magnets broke out of the sole in a few spots. I wrote Nikken (I believe these are supposed to be lifetime warranty when I purchased them) and I don't think I ever got a response.

Have used this product my this manufacture for over 20 years. These things are incredible. I have so much energy during the day when wearing them. Do not recommend though to wear on long walks without good socks!
