The Radical x Boa is the flagship of K2's training collection and is full of details that will make skate fans freak out. This includes an ultra lightweight and breathable version of the K2 Original softboot as well as the Boa lacing system that ensures outstanding comfort and is easily adjustable even on the go. The performance Hi-Lo technology does not only ensure a fast skate but it also lends it the agility of it's shorter competitors. The radical cuff gives you that extra bit of support to stay ahead of the rest at all times.  

The Radical cuff for high-end training skates needs to fullfill different requirements than other cuffs: It needs a flat profile and an overall lightweight that enables the skater to make perfect use of his technique. The radical cuff ensures all that and offers perfect suport on top of all that.

While the design of the Inlineskate was refined over the years, the most important aspect, the lacing system was neglected. K2 on the other hand never neglected this important detail. The unmatched fit of our revolutionary orginial softboot design was improved by the implementation of the Boa- lacing system.  Compared to conventional lacing systems the Boa system facilitates a much better fit and a locks the skate with a simple twist. The Boa system is individually adjustable, perfect for finetuning and it saves you time by stripping on andoff easily. Just try it, we are sure you will be upgrading to Boa soon!
