The Ricta Clouds are the most popular soft cruiser wheel for skateboards on the market! They come in a wide array of colours and durometers! Every colour correlates to a different durometer (hardness). These wheels are great because they're the shape of regular skate wheels and can go on a normal skateboard and you can still do tricks with them, but they are all in the "soft wheels" catagory, which means you can ride them on a lot rougher ground than a hard skatepark wheel (99D-103D). These are a versatile all terrain wheel you can rip to work on and still cruise through the skatepark with.
