The MOB "SKULL" Wheels are especially designed for skating "imperfect surfaces" as it is ever more often found at DIY Spots, ditches or abandoned industrial sites. With the "Ghetto" Wheel you can skate anything. - AND: since the wheels are a tad softer than your regular street wheel they also make a great ride for Kids skateboards.
