The UltraBoost sneaker gets a fourth redesign for August 2018 as part of the 'Show Your Stripes' pack. The aptly named UltraBoost 4.0 comes fabricated from a Cloud White Primeknit upper with matching TPU cages. Tech Ink and tonal Three-Stripes logos are emblazoned on the tongue, toe guard and sides. Detailed with metallic branding, an Ash Pearl heel cup structures the counter. Signature boost cushioning and Continental rubber are combined in the sole to offer enhanced comfort and support.
