Here's a short article about how they came about over here. Sounds like a great place to work.

Being a horsewoman, I've always seen them worn around barns but never bought a pair until I found barely used ones dirt cheap in a thrift store ($15!!!). Been in love with them ever since and will always have a pair.

Lately they have changed and are being made in cheaper countries. Mine are older and I can see a difference when compared to newer ones. To get a pair made by the original maker, you have to buy Sanitas.
