Around here they are usually worn by the kids, since they're cheap and proper show attire with the jodphurs for the under-12 set.
I have a set of steel toe boots from WalMart for really deep mud, but I'm thinking about a pair of camo Remington wellies for the dog stuff . . . cause they're thin enough neoprene that when it gets hot you can just cuff them down so your legs can breathe.
I have a pair of everyday men's workboots for mucking about in the barn, and a pair of insulated workboots for the winter that keep my feet beyond toasty. But when I ride I wear a pair of jodphur boots because they sure as heck beat pulling on a pair of tall boots, especially in the summer. I pull up my socks around my breeches so that I don't rub my ankle.
