Clean Calfskin Rider's Shoes

The colorset for these shoes has lots of dirt, and the dirt doesn't dye with the rest of the shoe. I made the dirt the same colour as the part it's on, with the same specular color/strength, changed pure blacks/whites to off-black/white, and made the shoes more matte.

(On install, it says only Male Hyur, but all the races and both sexes use the same textures. The image shows the dyeable part of the shoes as blue for demonstration purposes, but they come in two-tone black.)
