There are companies that offer snake boots in women's sizes out there. I plan on buying a pair of Irish Setter Vapr-Trek sometime in the near future. As for the price that's just the nature of the beast, they are going to be $200 or higher. The way I look at is even if you have awesome insurance a single venomous snakebite is going to cost you a fortune in hospital fees. If you require antivenin the cost goes up exponentially. A single vial of CroFab cost over $3,000 and the victim often requires multiple vials. Then add all the additional costs and you are well over $100,000.
$200 is a tiny price to pay in comparison.
