The new Reebok Zoku Runner Ultraknit keeps right on running into the summer months ahead with not one, but two new colorway packs that just dropped today. With four colorways total, the debut knit sneaker from Reebok that combines heritage with today’s sneaker construction trends is featured in two versions for the “Gum Pack” with black or white uppers and gum rubber soles and a “Lux Pack” with subdued brown and off-white uppers, translucent cages, and premium tan leather detailing at the heel. All four options are available now for $115 at Reebok.com.
