They are a few types of training shoes.. I own a pair of Nike Free 7.0 Trainer (used for hockey training). I use them for workouts. When I bought them I was told by the person assisting me by wearing them it would strength me foot muscles, improve spped, and improve agility. They are very light and comfortable. Basically, they are for training. Which is in the name (cross-TRAINING).
