Adidas UltraBoost 4.0 Legend Ink Blue Athletic Running Shoe 。UltraBOOST Laceless builds upon the signature styling of the UltraBOOST, adding new elements of stability and structure that do away with the need for conventional laces entirely. Instead, this new model features what look to be elasticised bands woven through the mid-foot – upping the \'stripe\' count from three to ten in the process. To add to this, an elasticised collar is fixed to the Primeknit upper for a snug fit – sans laces.
