Fragment Designs Kazuki Kuraishi continues to work with Adidas Originals to create the new 'Retrograde Resistance 84-Lab' line. This time round, the Japanese Streetwear designer takes inspiration from horse-riding, polo, football and hunting and the classic silhouettes found in these sports. As with anything Kazuki, the attention to detail and level of finish is impeccable. The ZX Riding Boots, fuses Adidas's ZX running shoe, with traditional riding boot details. Premium aniline leather uppers sit atop a trail running outsole, and are finished with an ankle strap that hosts an antiqued metal buckle.
