: Geared towards 'street' with a slider
Starway in Switzerland also has sliders. They attach to the kingpins, however. My street skates are from Starway and I have their sliders. While I like the skates, I'm not that happy with the sliders. They don't work too well and when a stone gets caught between slider and wheel the skate can block in a very nasty way.
