These do help with slipping, but not as a cushion.  I am a DDD so I have red marks on my shoulders constantly.  This did not help with that.  A few times, they worked loose and slipped into my shirt.  I can't figure out how that happened, but they did work to get the straps in place when I wore a shirt with a wide opening and move the straps out.
