About the Overtime x adidas UltraBoost 1.0 'Iridescent Stripes'

The Overtime x adidas UltraBoost 1.0 'Iridescent Stripes' features a black Primeknit upper with contrasting white threads woven into the side panel and toe box. Iridescent three-stripes shimmer on a black midfoot cage integrated into the lacing system. Overtime's 'O' logo appears on the tongue tag, while the company's tagline — 'Don't Be a Fan Later' — is inscribed on the heel tab. The sneaker is mounted on a responsive Boost midsole, painted black and supported by a grippy brown rubber outsole.
