This is their official product description from Powerdyne:
Moonwalker Toe Stops from Powerdyne are designed in a distinct "tear-drop" shape which gives more flex, bounce and extra control. The signature dimples on the stopping surface offer more bite when stopping and starting. Every Moonwalker toe stop is made from a natural rubber compound that is bonded to a lightweight aluminum stem for outstanding durability and consistency on every skating suface including wood, sport tiles, cement and outdoor surfaces (moon surface testing TBA....) Moonwalker toe stops join the PowerDyne lineup in 3 unique colors Mint, Electric Yellow and Blood Red.
|Holy toe stop holes, Batman!|
They're also pretty fat stoppers, which makes running on toe stops (and also pushups on toe stops, planks on toe stops...) slightly easier to do. I think the only other thing I can think of that is better for toe stop fatness are the Snyder Speed Stop toe stop, but that's also because they're toe stops with a big flat piece on the end. These ones are fatter than the regular Snyder ones, and I think about the same size as the Gumballs. There's less material in these ones though, because they're not completely round like the gumballs are, but kind of taper towards your skate. I don't think that counts much for weight though.
|The red on the stoppers is slightly duller than the Diablo red. Boo.|
I think they're going to be a competitor for the Gumballs: they're equally as light (it's the aluminium bolt I think), and they're both soft and squishy and quite grippy. However, these ones seem to be slightly grippier than the gumballs, and don't seem to mark as much (in my "rubbing both of the toe stops hard on a glass surface" test), for what that is worth. Plus, they come in cute colours.
