Now THIS is an unusual item!
This is a seldom seen pair of Sonic rollerskates! For some reason, like the skateboard, these are super rare. They were made somewhere in the UK, and have a "Hedgehog with Attitude" slogan on the side. The tops are the familiar checkering, and the velcro band to keep it on is decorated with Sonic's name and some sihlouettes of running Sonic.

The front laces-cover is actually shaped like that foreward facing Sonic head, and has stitching around the edge to keep it tough. Though, instead of a face, one skate gets a Tails, and the other has Sonic vs. Robotnik. The heel has the HWA and star bumper design common to UK items. Why are the skates so rare? You can probably see the reason in the photos. They're beat up. Skates that are worn any, are likely fallen in as well, and they get scuffed up quickly--not ideal to keep and collect. Still, these have a lot of nice detail and an interesting design.
