脚垫的形状和尺码与爱车的大小要合适，尺寸过大或者过小都会在刹车过程中导致脚垫移位，容易造成事故。应该尽量选择专车专用型与有定位卡扣型的脚垫会更安全。同时应该避免选择过厚的脚垫，太厚的脚垫会增加离合间距，不容易把握好刹车或者油门。

The shape and size of the foot mats are appropriate to the size of the car. Too large or too small will lead to the displacement of the pads during the brakes, which can easily cause accidents. It should be more safe to choose the special type of the special car and the pads with the positioning card type. At the same time, it should be avoided to choose too thick pads, too thick pads will increase the distance of separation, not easy to grasp the brake or the throttle.
