I just went to men’s boots, due to my bunions. Wider. I wear paddock boots and chaps. I don’t show, so no need for tall boots. Maybe this approach wouldn’t work with tall boots, due to men’s calf sizes normally being wider. No idea.
I wear Ariat Devon Nitro paddock boots. Great boots. Really and truly are waterproof. And comfortable, at least for my feet.
In a women’s, I wear a 9 1/2. With men’s boots, an 8 is the same size. Their stock medium in men’s would likely be a wide in women’s.
Had to get wider stirrups also, to accommodate the wider boots. But my feet are now WAY happier.
