Product review (5 stars): Simple way to lock down your walking washer using vibration feet pads
I wasn't sure these would solve the problem of my front load washer disco dancing almost every time, I have a week's worth of pants washing. For years, I simply "locked" the washer in place with a couple of small pieces of wood screwed into the floor blocking the feet movement. Since I finally got tired of hearing the washing bang around like a caged animal wanting to break free, the search for a better solution lead me to trying a few different rubber foot dampers.

I first tried the square Diversitech MP4-E E.V.A. Anti-Vibration Pad, 4" x 4" x 7/8"

I wrote a review for those but let's say, they quieted down the vibration but still allowed the washer to move around even more.

Then I tried these made by ENJ Products Washer Anti-Vibration and Anti-Walk Pads VIBRAFIX

I have a review up for those as well, but it basically the round feet with a "cup" held the washer feet and quieted down the vibration noise even better than the Diversitech ones but the washer still walked. Not as much as the Diversitech but moved several inches.

I was contemplating gluing the washer feet but then saw these adhesive pads. My initial thought was how can these glue pads keep a hundred pounds of machinery spinning at several thousand RPM from moving? I figure for the cost, I was willing to give it a try.

Cleaned the linoleum flooring, wiped it down with rubbing alcohol and then lined up the feet. Marked the floor with a marker and then wiped down the floor one more time. While tilting the washer on one side at a time, we applied the adhesive pads and stuck them to the marked locations. Set the washer back down on the rubber feet and now enjoying a much more quiet washer experience and NO walking any more!

Pros: simple idea. No special tools required

Cons: a little pricey for what it is but does the job.

Overall: recommended and works great with their matching rubber feet
