グレンソンさんのインスタグラム写真 - (グレンソンInstagram)「A look back at our olive tanned leather project. This collection uses newly developed materials that all improve on those that already exist. The upper leather and the linings are tanned using the moisture from Italian olive leaves instead of more harmful chemicals. The soles are rubber and made from 25% recycled material, the midsole is made from natural crepe, the welt is 100% natural rubber and the reinforcements in the toe and heel are made from recycled ocean waste.⁠ ⁠ #grenson #grensonshoes」5月16日 18時00分
