About the Stone Island x New Balance Furon Elite v8 FG 'Boulder'

The Stone Island x New Balance Furon Elite v8 FG 'Boulder' continues the partner brands' collaborative efforts with a performance soccer boot. Offset lacing secures the beige Hypoknit upper, featuring a durable polyurethane film with an integrated ripstop texture. Tonal 3D screen-printed logos adorn both the medial and lateral sides. Reflective yarns are woven into the knit collar and heel tab for enhanced visibility in low-light conditions. The outsole plate utilizes a 12-stud configuration, highlighted by T-shaped studs for multi-directional grip.
