LOS ANGELES (CBSLA) — Vanessa Bryant wants answers from Nike after a shoe she worked on with the company to honor her late daughter, Gianna Bryant, appears to already be in the hands of some buyers.

In a statement posted to Instagram, Bryant says she worked with Nike on a shoe that was going to be called the “Mambacita,” an exclusive black-and-white colorway based on Nike’s Kobe Bryant’s Black Mamba line. The shoes bear a gold 2 for the number she wore on her jersey, Kobe and Gigi on the back instead of Kobe’s signature, and inner details like a butterfly, wings, and a halo.

“The MAMBACITA shoes are NOT approved for sale,” Bryant wrote.

Bryant says she wanted all proceeds from the sale of the shoe to benefit the Mamba & Mambacita Sports Foundation, but decided not to sell or even make the shoes when she opted to not re-sign with Nike, a decision she says her husband was considering before he died in a January 2020 helicopter crash that also killed 13-year-old Gianna.

“Nike has NOT sent any of these pairs to me and my girls. I do not know how someone else has their hands on shoes I designed in honor of my daughter, Gigi,” Bryant said.
