The Big Bloc Toe Stop by CRAZY SKATES is not only called big, it is really BIG! The footprint of 54mm in diameter is gigantic,and it is beveled so that the braking effect is maximized. Due to its special and innovative dual density construction they give extreme grip and stability in one. The clue is that they're made out of two rubber compounds with different hardnesses. The soft (red) part provides for extra grip while the slightly harder (grey) part supports long lasting and prevents too much yielding. It is suitable for any surface and non-marking. Because of the 30mm stern length the stopper can be optimally adjusted to the required height!
