just pull them up
You need to pull leg warmers up past the gribber on your shorts. I put on my shorts, roll them up, pull the leg warmers far up, theanen roll the shorts back down. The elastic in the shorts prevents the elastic in the warmer from sliding down. I use to have problems until an old timer showed me how to do it right. I had given up on them, now I can't live without them. They are so versatile, a cols morning ride that turns into a warm afternoon ride is no problem any longer. Try it. They are a geeky but functional item.
