Christian Louboutin’s YSA boot ($1,495, Barneys New York) is red hot for fall and winter. This is a smooth leather taper toe pull-on knee boot with tonal stretch suede paneling in a rich red hue. The monochromatic red look is given texture by mixing the smooth leather and suede. The skinny 4-inch heel keeps the boot feeling feminine and not too heavy. Pepper up your look with these fabulous red boots. If red isn’t your thing, they also come in black.
