In essense the Aeon is a body, cuff, liner, and wheels. The Aeon is designed to improve grinding with larger wheels, and to bridge the gap between aggressive, powerblading, and free skating. By eliminating the UFS mounting system and simplifying the body of the skate, USD reduced the number of parts which has ultimately increased durability. Less hardware under the foot gives the skater a lower center of gravity which provides increased control.
No more swapping frames, with the Aeons you can roll from one spot to another without taking off your skates!
