Ankle straps are really big for fall, but so are flats. I chose this pair because the mix of snakeskin and tan means they could easily be worn now and during the fall. They also come in tan and black and patent red and tan.
The Olivia Flat from Need Supply Co. has taupe suede on the front and metallic on the rear. This inexpensive Charlotte Russe flat has a mix of black leather and suede. And this pair of t-strap flats from Aldo is also a great choice.
Prefer a heel to a flat? These Nine West Callen heels are pretty fantastic. This Sole Society pump with pyramid studs is a favorite. And if you want something for summer/fall, this inexpensive cognac sandal is so chic.
