I modeled this to more or less follow the topology from the CG Cookie tutorials with a couple minor exceptions. There's a little extra geometry at the ankles for detail, and an extra loop at the toenails to hold the shape better. I removed it from a WIP model of mine that is 1.7m or 5'7" tall so it's to scale. No textures, but it does have UVs. They're not great as I haven't learned proper UV unwrapping yet, but they should work well enough to paintover if you don't want to unwrap it yourself. Sketchfab doesn't offer a CC0 option, but I've listed as CC0 on Blendswap, and as far as I'm concerned, it's CC-0 here as well. Update: found an issue with the topology markers, so I fixed it and cleaned up a couple other minor issues. Now if you turn of the wireframe with the model inspector, you can see the subdivided foot's shape more clearly. Need a hand? I've got [one of those](https://skfb.ly/o6GtF) for download too.
