How to Choose Shoe Width Wisely?
Equip your machine to handle the condition of the specific environment, using the narrowest shoe possible that still provides adequate flotation and function.

A shoe that is too narrow will cause the machine to sink. During turns, the back end of the machine slides, causing excess material to build up on top of the shoe surface which then falls into the link-roller system as the machine continues to move. Tightly packed material built up on the roller frame may cause reduced link life due to the link sliding across the packed material, which may also cause the carrier roller to stop turning;
However, a slightly wider shoe will give better flotation and accumulate less material because the material is farther away from the link-roller system. But if you choose shoes that are too wide, they may bend and crack more easily, cause increased wear on all components, may cause premature dry joints, and may loosen shoe hardware.
