If you liked the 5th Element Panther XT Inline Skates but a little better performance, then these are the boots we would recommend.
They have slightly bigger 84mm wheels and upgraded ABEC 7 bearings. Should you start out with these sets of boots but find yourself want a little more, then you can easily up their performance by upgrading the wheels to 90mm. This will give you plenty of extra performance that even a confident intermediate would be happy to have.
