I have a set of Driver-X from ~2001 or so. They are a very stiff boot and were fantastic for freeriding.
However, this year I found the Burton Ions to be a little softer and more usable in the park situations.
All that being said. Boots are mostly about comfort and support.
Everyone is different and you should try on every boot you see.
I think I tried on about 20 different pairs of boots this year before I bought the Ions.
Hey thanks for your reply. Yea, I've been riding the x's for about 3yrs now with my old DH board and have found them super comfy. Altho I have advanced pretty well and wasn't sure if stiff boots can hold you back. Some say yes and some say no!! Ion's in uk are about. £250 and my x's were £210 so it needs to be worth the change to go down that road. I only ride once or twice a season as we don't get snow much ere. What would you do?
