If you want to do up your skates with the standard Rollerblade strap after fitting replacement liners like Jug or Reign liners, you can simply cut a new hole in the cuff, 2 inches further round the cuff. Make it the same size as the original mounting hole. Use a sharp stanley knife. If you're young, get a parent to do it !! Don't make the slot too big or the strap won't stay in place when undone !

The strap simply clips into the slot, so you can remove it and insert it into the new slot that you've produced.
