In August 2015, Yohji Yamamoto's collaboration with adidas, known as the Y-3 line, introduced the stylish and futuristic Y-3 Retro Boost 'Roundel Blue' sneaker. This sleek shoe features a plush neoprene upper adorned with suede and leather overlays, as well as a distinctive striped mudguard. Midfoot pieces with branding are cleverly integrated into the laces to provide extra support. Additionally, a comfortable suede lining and Boost midsole offer cushioning for the foot.
