Zeke’s neon stripes made him stand out as a target, so he was kept at the back of the herd and branded a walking target.

But one stormy night, chaos struck, scattering everyone into the dark. His glowing stripe became their beacon, guiding them back together. From then on, Zeke wasn’t just different, he was celebrated as a hero.

    Can’t get him out of them

    I got these for our 13 year old so and he loves them.

    A great style, which he has raved about, and super comfy. There’s nothing about these Knobbys he doesn’t love.

    I was a bit nervous about all the pink and purple in the design, but the rad artwork has hit the spot for him.
