Poured in Seismic’s Premium Pool/Park urethane formula.

Somewhat wider than most wheels of their height, and with a slightly offset bearing seat, the 58mm by 37mm Boosters offer breakthrough performance for modern pool and park skating. Poured with the world’s most advanced no-flatspot formula, and machine-ground for that perfect broken-in feeling. Great for hard-wheel sliding, too!
