Width Area: Foot is supposed to fit comfortably without stretching the upper over the midsole of the shoe.
Heel Area: Heel can move but is not suppose to slip.

Training shoes are commonly referred to as cross training shoes and can be used for a variety of sport activities.However these shoes aren't meant for continous running, because they're heavier and don't offer the cushioning and flexibility runners need.
