The Explorer Inline skates are designed for recreational inline skating – made for adults! The Black & Yellow are in Men’s sizes (6-12) and the White & Teal are in Ladies’ sizes (6-10). The boots have power straps for a secure fit and deluxe comfort liners for when you are cruising. The frames are a lightweight reinforced polymer material – keeping the overall inline very stable. Designed for indoor/outdoor use – the wheels are fairly large at 76mm with ABEC-7 bearings, you will especially love them for trail skating or the roller rink showing off your moves! The inline skates are very lightweight, so this makes them easy to wear no matter how long you are skating; so strap up your Pacer Explorer Inline Skates before you head out!
