K2 Radical 100 M

Pin It Fancy

The Radical 100 M is viewed as the model that has defined what advanced, to expert big-wheeled inline skates are supposed to be; light-weight, fast and stable. The Radical has earned its excellent dampening and light weight properties thanks to its glass fiber base, Radical Aluminum alloy frame with 100mm wheels and the Radical cuff. It also has the benefit of K2’s Softboot® design that creates maximum comfort needed when skating for hours at a time.

K2 Skates generally fit true to US sizes. For example, if your shoe size is US size 9, you would wear a size 9. A snug fit is always preferred so be sure not to buy oversize footwear especially for skating. Children skates are expandable so do refer to the junior expandable sizing table.
