The design of the “Crutch" is very important to avoid slipping during walking for the disabled on different floors.  It is known that the uses of crutches are limited to specific floors. The recent research aims to redesign and optimize the pads for these crutches to extend their uses on different floors. Fabricating small grooves and surface modification in specific patterns are suggested approaches to increase the friction and the adherence properties between the crutch's pads and the different types of floors. Furthermore, metallic elements could be used side by side with the grooved rubbers. The frictional behavior of different pads with different designs has been simulated to observe the sticking mechanism of these pads. Moreover, the optimal design has been obtained. In conclusion, the recent research suggests a new design for the crutch pads to offer a safer walking practice for those people who use the walking aid equipment.
