For a great all-purpose Stroller, these can't be beat! Swivel Wheels with Lockout function best as a swivel wheel, for maneuverability they are functionally identical to the Swivel Wheel. When locked out, they simulate the Fixed Wheel. However, many still shake a bit when locked out, so if you'll be using your Stoller more for running than Around Town, you'll probably want a true Fixed Wheel Stroller.
