Light waxed skate laces. Waxed hockey laces can be difficult to adjust at first because they're kind of sticky,
but they "break in" as the wax softens, and they tend to last a lot longer than uncoated laces.
These are kinda like already-broken-in hockey laces. Recommended for derby warriors that play on asphalt or unpolished cement.
Will fit most Roller skates across brands and manufacturers.
