    Comments:Fit great, skate great, well made. Soft sides feel good but get torn up when you fall. (Personal experience--Ouch.)
    From: Bob, Atlanta GA, USA

    Comments:I recently purchased a pair of K2 Radical 90's (2006 model). The skates are EXCELLENT! there were no "break-in" issues, comfortable right out of the box, and yes, really fast. I purchased one half size smaller than I actually wear (thanks to another reviewer) and got used to the longer frame within a few days. The delivery was fast and will use inlinewarehouse again, thanks.

    Comments:Awesome skate. Bearings and wheels are superb and speed is excellent. Only one thing I'm not thrilled about: boot puts a little too much stress on ankles. Other than that, awesome. Inline Warehouse satisfaction-excellent. Really fast shipping, excellent condition.

    Comments:I have been training with these Radical 90's for a couple of months, and absolutely love them. They're fast and very comfortable for long skates. The workmanship is very good and wheel and bearing quality is also very good. My only issue thus far is that the straps for the buckles are being chewed up must faster than I would have expected and I will no doubt have to replace them. Aside from this, a very nice skate.
