Y-3 Reworks the adidas Originals Forum Hi OG | Hypebeast。Yohji Yamamoto\'s take on the retro basketball shoe emerges with a blacked-out look on the Y-3 Forum Hi OG \'Triple Black.\' Built entirely with leather, the shoe\'s monochromatic upper is secured by an ankle strap, with zippered detailing running around the heel and down the lateral midfoot. Underfoot, a Forum-style rubber cupsole includes an EVA wedge on the medial side, overlaid by Dillinger webbing, to provide cushioning.
