Ad-Rock has teamed up with Los Angeles footwear company Keep for a new shoe. The Ad-Rock Ramos is designed to keep your feet warm during the winter. It features a water-resistant, nylon cordura body and is lined with synthetic shearling.

The Beastie Boys member, who led an anti-hate rally earlier this month, plans to donate the proceeds from the new sneaker to Planned Parenthood. The veteran MC explained his decision in a statement about the new shoe.

"Winter’s cold and I couldn’t find a warm sneaker to walk around in," Ad-Rock said. "Given the outcome of our current election, it’s gonna get a lot colder before we can feel that summer sun again. So I collaborated with my friend Una [Kim, founder of] Keep shoes not just because I wanted warm sneaks, but because I support small business. I support women run business. I support Asian-American run business. Net proceeds of this shoe will be donated to Planned Parenthood because I support a woman’s right to choose and feel that women should not be punished for making decisions about their own lives and bodies. If you have similar beliefs, you might wanna grab a pair. Or, if you simply support fresh styles, then you too can be part of what peeps in Keeps are doing."

The Ramos Ad-Rock can be pre-ordered now at Keep's digital store. The sneaker will ship in February and is available for both men and women.
