In Las Vegas, we don't have to worry about hiding our legs from the elements such as wind, rain, sleet or snow. When the weather cools, we only have to concern ourselves with looking fashionable. And for fall, that includes riding boots. This trend showed up on Rachel Bilson last fall and has warmed its way into our closets. Riding boots provide the true crossroads of function and fashion. Should you make a jaunt out of town, these boots will keep your legs warm and dry. Might as well break them in now, cowgirl.
