Weight training requires a special kind of shoe. Most "trainers" are for running or speed sports: thick cushioning and a high heel-to-toe ratio, designed to propel you forward.  For stability and proper muscle recruitment during weight training, you want a "less cushy" sole and a lower heel-to-toe ratio (how much higher your heel is than your toes). These Dropsets by Adidas are the best weight training shoes we've ever used!
