LEGO Shop At Home Online is offering a great deal on ONUA sneakers. At 50% off, the sneakers are less expensive than the usually-less-expensive ONUA sandals. Problem is, all of the sizes are currently listed as “Sold out” or “Call to check product availability.” Since a shoe or sandal is the only way to get an ONUA mask, it is not surprising that they would be quickly snapped up at 50% off.
