While she lets her outstanding play do most of the talking, Serena Williams is also known for bringing her unique and trendsetting fashion sense to an otherwise vanilla sport. While most tennis players primarily wear white, Williams has brought splashes of color in her outfits and her shoes. Previously with Puma and now with Nike, she has had much impact on design and colorways. Here are a pair of her most popular Nike shoes. They are from the Flare design line with the classic pink color tones she has made popular. Williams has autographed these pink Nike Flare shoes in black paint pen. Her signature is deemed authentic by virtue of Upper Deck Authenticated's Five-Step Process.
