Clean and cohesive, these BOSS Menswear trainers feature snug knitted uppers for enhanced support and breathability. Ridged EVA-rubber outsole delivers flexibility, responsiveness and comfort. This product contains at least 80% better raw materials. This product is partly created with recycled polyester. We at HUGO BOSS prefer recycled polyester from pre- and post-consumer textile waste and do our best to phase out polyester from PET bottles.
