If the last set of boots is what you're call Caiman - that's ostrich leg. There are not any caiman boots in the photos.

User name checks out, real cowboys don't wear square toed boots.

Shape of toe has become nothing more than a fashion preference to the casual boot wearer, i will admit to that.However, shape of toe (square v. Round/roper) has origins and distinct advantages depending on what exactly the cowboy is doing while in the saddle.

Basically if a cowboy is trying to stay in the saddle (rough stock) square toe v trying to dismount smoothly (tie down roper) hence the "roper toe or ropers.

So real cowboys wear all sorts of toes on boots. While we are at it, types of heals on boots are more than a fashion statement as well to the cowboy.
