Rollerblade Spiritblade Recreational Inline Skates Hyper Wheels Active Brake Technology. They have Hyper Fat Boy wheels that have a fair amount of wear (please see photos). There is no size on these that I can see. The removable boot liners measure about 11.5" long and the outer hardshell measures about 13". I would say they are a Men's size 10- 10.5.
