They are definitely not non-slip, as I almost killed myself walking over a metal grate the second day of wearing them. The only regret I have is that I did not replace these pads a year ago when they started breaking down. I would have much preferred the same textured plastic on the sides as on the top. That got to be pretty expensive! Very tricky to use on my devic Bought these for my Solo 3s since the case provided by Beats was too soft and tight. Ill add that I was told I dont have very thick fat pads on my feet, so the cushion in these allowed for so much pressure to release from my feet and legs. I bought this product thinking a was getting a good deal. The only reason Im giving 4 and not 5 is because they took work to make work. This device is totally inferior to the Apple iPhone magnetic charger.
