These are my 13 ish year old Bauer supreme 4000's, Used them on ice for years then converted to roller. They've been like this for 7-8 years....served me well over the years I really don't like the chassis, I've always had the shock locked, but the rubber spacers are starting to ware and my rear wheel does have some side play, which is starting to affect skating I'm finally retiring them next week from indoors....ordered Bauer xr4's Funny thing is, I bought the xr4's last week and didn't realize that some of the threading on the boot where it meets the toe cap was coming out and loose, I returned them and waiting for a new pair ...pretty weak, these killers don't have one thread frayed and have been beaten to death. By the way, the pink laces are from when our team was 'the pink panthers' a few years back
