Ditch the cross training shoes. The squishy soles in those type shoes as well as some running shoes does no favors in the deadlift. Scott has several videos on how to setup the deadlift and many tips to improve. Bare foot or wrestling shoes are listed in the videos. I have only been deadlifting for about four months and when I ditched the shoes i instantly found a new level of stability and controlled strength. Good luck and keep up the great work!
