Atom Boom Wheels are back! These once-popular wheels were revived in 2025 and once again offer skaters an all-in-one wheel that provides reliable grip on a variety of surfaces. The thick tire and innovative urethane formula that Atom uses here work together to provide a lot of natural traction. The "X-Firm" hardness that Atom assigns to these Boom Wheels skates like a low-to-mid 90s on the A durometer scale (91A-95A), in our opinion, which gives it versatility on a range of skating surfaces such as polished concrete and slick wood floors.
