A conformation flaw in which the front of the foot faces out, often causing the leg to swing inward during locomotion ("winging").
A wheel alignment adjustment to control the way the car tracks on turns. Tires should never be toe-out.
Part of the kart setup which can dramatically affect handling. Toe-out means that the front of the front wheels is further apart than the rear-end of the front wheels. Essentially, it looks like the two front wheels want to drive away from each other. Toe-out will make the kart dart rapidly into a corner when the steering wheel is turned. Toe-out is not recommended. See alignment and toe-in.
