In this example, we used a fleece on the outside and a fairly thick fur cloth on the inside. For practical purposes, it would be better to choose a stronger cloth than a fleece, such as heavy thick wool. The shoe sole was used with the normal leather turned inside out, but suede is more suitable because powder does not fall easily. Synthetic leather is also nice, but it seems to be more frayed than real leather. Genuine leather shrinks when washed, so washing can be done by hand quickly.
