Goalie wheels are made for inline skates designed for roller hockey goalies and are available in 47mm or 59mm. Some wheels have rounded profiles for agility and some have flat profiles for stability. For goalies using player skates, use player wheels sized down as much as possible while maintaining the wheel difference. Example a 80mm/76mm Hi-Lo skate can take 72mm/68mm (4mm difference). This helps the goalie be more maneuverable and get closer to the ground.
