I just use that grip you get on rolls at the grocery stores and Walmarts and dollar stores. You can just lay a strip down or attach it to the bottom of the pedal. I just put a piece under the pedal. I use it for a lot of things like keeping cutting rulers and material from moving when trying to cut. I've gotten as much as 2 yds. for a $1.00. You can buy larger rolls. Also things on wheels or casters don't move at will as much either. you can also buy a small rubber car floor mat and use that.
