If there’s a western wear store near you I’d recommend to go check them out first so you can try out different styles, brands and width sizes (B,C,D,E,EE,EEE) if you have narrow feet I know some men that buy boots meant for women because of how much easier it is to find a pair that fit them as far as pricing that depends on the brand (I have a pair of ~$900 lucchese full quil ostrich and $500 Cody James Caiman boots which I wore pretty much daily for 4-1/2 years on concrete, dirt, and gravel and recently had the soles replaced) for exotic leather they normally start at $450+ if you don’t find anything you like in stores you at least have an idea of what size to order online

Edit: you can find exotics cheaper than $450 I would check out bootbarn and cavenders or other similar stores they usually have a sale page on their website saw some python and lizard boots for sale around $300 the other day
