Labeda Addiction XXX 150 Inline Hockey Wheels - 4 Pack 2010 - The Labeda Addiction 150 XXX hockey wheels revolutionize the future of indoor wheel designs. Perfect for tile surfaces the outer urethane is as hard as most outdoor wheels increasing the life of the wheel. Yet Labeda was able to make this hard wheel grip as good or better than most indoor wheels available. It is a contradiction that works perfectly and once you start using the Addiction XXX wheels all others will seem obsolete.
