Lift Slider - Ts3

Why does some shoes say "needs lift slider"?

Some shoes mesh sink in the floor, they need the lift slider to lift the sim above floor, this way the shoes won’t stay below the ground. The lift slider works two ways. In cas you lift the sim, and it lifts to all categories. In game, you click the sim -> lift sim and enter the number of the height you want to lift. For exemple, -1; 1; 1,5; 2. The number 0 is the regular height. This method only lifts the sim in the present category. Unfortunately this method doesn’t work for males.
