The main reason behind the wear and tear in shoes is fatigue. It's the weariness resulting from exertion; repetitive movement cause the fabric, rubber or leather to tear where in the area that is mostly compressed or stretched. Think of how you would tear a paperclip (intuitively) - by repetitive maneuvers of bending up and down around a spot, where it will eventually crack.
The effects of fatigue become more evident in case the materials the shoe is made of are chemically degraded, exposed to excessive heat or cold. Other factors are purely mechanical (accidental cracks, cuts, punctures etc.

Friction has advantage and disadvantage, In that case friction causes wear and tear. there are two activity to prove friction causes wear and tear. 1)some years back in a flight the nose landing gear failed. it turned sidewards, so when landing due to friction it caused fire and also the metal parts in the wheel was disappeared and also the the rubber tube was gone. so, this activity proves us friction causes wear and tear 2)when the car is travelling 100kmph and when the driver put a sudden brake the car stops after a few seconds but if we see the tires it will not be as same as before the driver puts a brake it smooth and it will not have the threads in the tire. The threads in the car are damaged so, this activity also proves that friction causes wear and tear.
